Dear reader,

It is not an exaggeration to say that without my great-grandfather Ferdinand

Adolph Lange, there would be no A.Lange & Shne manufactory nor would

Glashtte be a crucible of horology. His ambition to craftthe worlds nest

his own tools, measuring instruments, and machines and continually improved

his watches. In the course of the years, he succeeded not only in setting up a manu-

the impoverished region a new perspective. His courage, his thoroughness, and

his visionary thinking were the three main factors that made his company thrive.

The decimal minute repeater

mechanism

For supreme precision and reliability

When they developed the strikework for this watch, the engineers harnessed the prin-

ciple of the jumping numerals mechanism: instead of with hands, the time is displayed

with an hour ring and two minute discs. This allows three snails connected with these

mechanical display elements to sample the time to be acoustically indicated. The hours

are sampled on the outer circumference of the hour ring in which the twelve-step hour

snail is integrated. The tens-minute snail and the minute snail are connected with their

assigned minute discs as well. They are arranged on two separate axes and have ten and

six steps, respectively. The configuration and shape of the three snails with relatively

large sampling surfaces make it possible to decode the time in a dependable and error-

free manner.

The energy needed by the striking mechanism is not provided by an additional barrel, but

by the mainspring. When the strikework is activated, the ratchet wheel is uncoupled from

the winding train. Therefore, the ratchet wheel can turn freely and power the striking

mechanism. This also prevents the winding train including the crown from turning during

the repeater sequence, which would imply a loss of energy. The mechanism that un-

couples the winding train is one of a total of six new features in this movement for whichpatent applications have been filed.

The acoustic indication at 7:52 is composed of seven

low-pitched tones, followed by five double tones, andtwo high-pitched tones.

The mechanism that delays the switching action of

the numerals display prevents any interference with thestrikework sampling sequence.

Ingenious safety mechanisms

Engineered down to the tiniest detail

To guarantee the flawless interaction of the complex mechanical ensemble, elaborate

safety and blocking mechanisms have been integrated into the movement. While the

repeater is working, the switching action of the numerals discs is delayed. At the same

time, the crown cannot be pulled and consequently, the time cannot be set. This pre-

caution prevents any interference with the strikework sampling sequence and ensures

that the acoustic indication of time precisely corresponds with the digitally displayed

time. At 12:59 hrs when the longest series of tones is struck, it takes about 20 seconds

until the repeater sequence has ended. If a new minute begins while the repeater is

striking, the minute and/or hour jump is performed immediately when the tone sequence

has ended. Thereafter, the next numeral disc switching cycle takes place with the regu lar

timing when the continuously running seconds hand passes the 60-seconds mark.

Since the mainspring drives the striking mechanism, the number of minute repeater

sequences and their duration influences the residual power reserve. To assure that the

repeater sequence is not prematurely interrupted and the watch inadvertently stops

running, the striking mechanism can no longer be activated if the remaining power re-

serve is less than twelve hours. This blocking mechanism is activated when the power-reserve indicator reaches the red marker.

Configuration of the axes

A rattrapante chronograph has two hands seated on arbors that rotate inside each

other. The double rattrapante mechanism has two of these configurations for its two

seconds hands and two minute-counter hands. The following description of the

sweep-seconds axis applies analogously to the minute-counter axis.

The double rattrapante mechanism

The hollow chrono centre arbor on the outside (1) carries the chrono sweep-seconds

hand. It is driven by the movement via the chronograph centre wheel (2). It is rigidly

connected to the zero-reset heart cam (3) of the chronograph centre wheel and the heart

cam (4) of the rattrapante centre wheel. The heart cam makes it possible to reset a handto zero by taking the shortest route possible either clockwise or anti-clockwise or,

in the case of the rattrapante hand, to synchronise it with the chrono sweep-seconds

hand.

The rattrapante hand, which is superposed on the chrono sweep-seconds hand, is

attached to the inner rattrapante centre arbor (5). This arbor holds the disengagement

wheel (6) and the rattrapante centre wheel (7) to which the rattrapante heart lever (8)

is attached.

Starting and stopping the rattrapante hands

In the basic position, the rattrapante heart lever (8) is pressed against the flat side of

the heart cam (4) of the rattrapante centre wheel by a spring (9). This connects the

otherwise separately movable chrono centre arbor (1) and rattrapante centre arbor (5).

So when the chronograph is started, the rattrapante hands are started as well.

When the rattrapante button (10) is actuated, the column wheel (11) rotates slightly.

Now, the rattrapante split-seconds clamp (12) closes and arrests the rattrapante centre

wheel (7). An arresting spring (13) concurrently seizes and stops the rattrapante minute

counter while the two chronograph hands continue to move.

Function of the disengagement mechanism

Normally, the rattrapante heart lever (8) would now rub against the heart cam (4) of

the rattrapante centre wheel, which continues to rotate with the chrono centre arbor (1).

To prevent this, the master watchmakers developed the patented disengagement

mechanism.

Actuating the rattrapante button (10) also pivots the disengagement segment (14) inward.

This motion rotates the disengagement wheel (6) by about 20 in the other direction.

The bottom side of the wheel carries a pin (15) that when rotated in the opposite direc-

tion swings the rattrapante heart lever (8) out of the contact zone of the heart cam (4)

of the rattrapante centre wheel.

Synchronisation of rattrapante and chronograph hands

When the rattrapante button (10) is actuated a second time, the rattrapante split-

seconds clamp (12) opens and the arresting spring (13) is pushed aside. This causes the

disengagement wheel (6) to turn in the opposite direction, so that the pin (15) releases

the rattrapante heart lever (8). The lever then makes contact with the heart cam (4) of the

rattrapante centre wheel and comes to rest against its flat side again: the rattrapante

hand now instantly jumps to the position of the chronograph hand.

Grand and small strikes

The GRAND COMPLICATION is endowed with a striking mechanism that activates itself

at each full hour and every quarter-hour. The grand strike indicates the full hours together

with the quarter-hours. The small strike sounds the quarter-hours and only at the top

of the hour the hours. The strike mode can be chosen with a selector in the bottom case

flank. The letters refer to the German terms: G stands for grand str ike, K for small

strike. The selector at the top of the case allows the striking mechanism to be engaged

and disengaged. S stands for strike. R means rest; in this position, the mechanism

is turned off. A separate spring barrel delivers the energy needed for 24 hours when the

grand strike is activated.

The minute repeater

The minute repeater is activated with the trigger at 8 oclock. This function indicates the

current time of day acoustically, to the minute. The number of low-pitched tones is the

hour count. Double tones stand for quarter-hours and high ones for minutes.

The tweaking and tuning process

The grande sonnerie mechanism is especially challenging for the watchmaker. He is re-

sponsible not only for precisely adjusting the switching sequences of all individual partsbut also for the richness of the sound. Tuning requires acute hearing and is performed

exclusively by hand to achieve sonority and reverberation of both gongs separately and

perfect harmony in unison.

The chronograph function

The chronograph button in the upper right-hand case flank is used for stopwatch meas-

urements. When the button is actuated, the measurement begins; the stopped time

is displayed when it is actuated a second time. The small blued hand in the upper sub-

sidiary dial indicates the measured minutes, the blued chrono sweep-seconds hand

a second to an accuracy of one-fifth of a second. All chronograph hands jump back

to zero when the button is actuated a third time.

The rattrapante function

The rattrapante button in the upper left-hand case flank expands the stopwatch

functionality. If it is actuated during an ongoing measurement, the blued rattrapante

sweep-seconds hand stops to display an intermediate time. The gold-plated chrono

sweep-seconds hand, concealed beneath the blued hand until that instant, continues

to run. When the rattrapante button is pressed again, the rattrapante sweep-seconds

hand catches up with the chrono sweep-seconds hand and then runs synchronously

with it again. This function can be repeated as often as required. It allows the determi-

nation of intermediate times and comparative times.

The flying seconds

The flying seconds is a mechanical rarity. Every second, this hand performs a full

revolution in five jumps. A specially designed escapement assures that the hand can

perform its movements in a flash, so to speak, and with the utmost precision. The

energy needed for this rare additional chronograph function is so considerable that

a separate spring barrel is needed to deliver it.

The precision of the perpetual calendar

On its dial, the perpetual calendar of the GRAND COMPLICATION indicates the date,

the day of the week, the month, and the leap-year cycle. Additionally, it features a

moon-phase display. All calendar indications are designed to advance instantaneously.

The mechanism knows how many days each month has in the course of a year and

is also aware of the fact that February has 29 days in leap years. The duration of each

month is coded into a 48-step cam with recesses that are mechanically sampled by the

date switching lever. The shorter the month, the deeper the recess.

The correction in the year 2100

The date must be corrected by one day, but not until 2100. In that year, the Gregorian

calendar omits the 29 thof February according to the rule that leap years are skipped

in secular years which are not divisible by 400. The adjustment is performed with cor-

rectors. All calendar displays with the exception of the moon phase can be advanced

by one day with the main corrector at 12 oclock. The corrector for the moon phase is

located at 5 oclock. Once the watch has stopped after being set aside for a lengthier

period of time, the displays can be conveniently updated with two additional correctors

that can separately advance the day of the week and the month.

The balance spring:

the component that determines the rateaccuracy of a mechanical watch.

Accurate is not enough

The production of balance springs is one of the most complicated processes in preci-

sion watchmaking. Only a handful of watchmaking companies master the operations,

among them the Lange manufactory, where particularly high quality standards are

attained. First, a metal wire is drawn and then rolled to a strip with accurately specified

dimensions. At Lange, the tolerance is one ten-thousandth of a millimetre, a hundredth

of the diameter of a human hair. In these minuscule dimensions, quality controls based

on laser measurements are no longer sufficient. To verify compliance, it is also neces-

sary to weigh a defined length of the strip with a precision balance.

Mathematical precision guided by hand

This strip is coiled into a raw spring, a filigreed component with a diameter of barely

5 millimetres. It is heated so that it will retain its shape. Then, the real challenge begins

the bending of the terminal curve. For the first time, Langes developers described the

optimised terminal curve with a correct mathematical formula. Despite this accurate

definition, the many individual bending steps cannot be performed by machines and

must be executed by hand. The tolerance range in the bending process is equivalent to

the thickness of the coiled strip: about two hundredths of a millimetre. It takes at least

two years of practice for a specialist to develop a feeling for the delicate material.

In 1799, German natural scientist Alexander von Humboldt embarked on his

legendary expedition to Latin America. One of his most important scientic

instruments was a chronometer built by Saxon precision watchmaker Johann

Heinrich Seyert. Its precise reading of time helped Humboldt calculate the

co-ordinates of his locations and perform many scientic measurements.

In the interest of good legibility under poor light conditions, he chose a modelwhose displays of hours, minutes, and seconds were arranged separately in

triangular fashion.

This characteristic feature of many Seyert chronometers

inspired Langes master watchmakers as they designed the R L

T Pour le Mrite.

Even later in life, Humboldt preserved his eagerness to advance the sciences.

In 1842, he suggested to Frederick William IV that special accomplishments in

science and art be rewarded with the most prestigious order of merit bestowed

in Prussia: Pour le Mrite. Even today, the distinction is still conferred by the

President of Germany. Langes masters use the attribute Pour le Mrite to iden-

tify the manufactorys most complex and precise timepieces."#$ R L

Exploded view of the fuse withits internal planetary gear system.

Harnessing the laws of physics

It is one of the tenets of physics that the power generated by the mainspring is high

when it is fully tensioned and significantly weaker as it nears the fully unwound state.

This can cause rate accuracy fluctuations. The fuse-and-chain transmission works

like an infinitely variable gearbox. It equalises the waning force of the mainspring and

makes sure that the movement always receives a constant amount of energy. This

keeps the watch running at an exact rate.

Force equalisation according to the principle of levers

The fuse-and-chain transmission obeys the principle of levers. The fuse is shaped like

a cone with a helical groove cut into its lateral surface. With full power, the mainspring

barrel tugs at the top of the cone, i.e. at the shorter lever. As the spring loses energy,

the chain reels offtoward the broader end of the cone: as the radius grows, the lever

becomes longer.

To guarantee that the watch continues to run even while it is being wound, the fuse

accommodates a tiny planetary gear system. It assures that power transmission is not

interrupted during the winding process, even though the fuse then rotates against

the unwind direction.

Optimising the drive

When the mainspring is fully wound, and briefly before the fully unwound state, the fuse-

and-chain mechanism reaches its limits. This is because in both cases, the torque delivered

by the mainspring fluctuates suddenly and incalculably. To assure the utmost in precision,

the power-reserve period is thus limited to the middle torque delivery range, where the energy

output declines uniformly and calculably.

Blockage before fully wound and fully unwound state

A blocking mechanism prevents the mainspring from being fully wound: a rivet (1) in the

chain activates a lever system (2) at whose end an arresting tooth (3) pushes into the ratchet

wheel (4). This blocks the fuse (5), which is rigidly connected to the ratchet wheel.

A second blocking mechanism stops the movement before the mainspring is fully unwound:

the power-reserve wheel (6) is the crucial element here. During the 36-hour power-reserve

period, it rotates by about 300 degrees. At the end of this path, the beak of a lever (7) drops

into the recess in the power-reserve wheel. Simultaneously, its other end (8) pivots into

the range of the blocking finger (9). It is connected with the fourth-wheel arbor and rotates

exactly once a minute. After no later than 60 seconds, it contacts the lever and blocks the

entire movement.

racy that if the watch runs without interruption, it will take 1058 years before

a correction by one day is required.

In the centre of the celestial disc, the earth disc rotates through 360 degrees

once a day. It is daytime on the half that faces the sun (the balance) and nighttime

Constant power for two weeks

With two strong springs, the twin mainspring barrel of the RICHARD LANGE PERPETUAL

CALENDAR Terraluna provides a power reserve of 14 days. When fully wound, the

torque delivered by this high-energy mainspring barrel would be much too high to be

transferred directly to the going train. And as its torque declines when it approaches the

unwound state, the accuracy of the watch would deteriorate. To keep the rate of the

watch stable for the entire power-reserve period, a patented constant-force escapement

is integrated between the twin mainspring barrel and the going train of the calibre L096.1.

It causes the twin mainspring barrel to output a small amount of energy every ten seconds.

This energy retensions the remontoir spring by an angle of 60 degrees. It absorbs the

exact amount of energy that it will transmit to the escape wheel, the lever, and the balance

spring within the next ten seconds. Since the remontoir spring always releases exactly

the same amount of energy, the watch is powered with the same torque every day. The

result is a constant amplitude and thus an especially high degree of rate accuracy.

The remontoir spring of the constant-force escapement and the balance spring are both

manufactured in-house and can thus be optimally paired with the movement.

1. Arrival at the Service Centre

When your watch arrives at theService Centre, its condition is

assessed and recorded. It is then

uncased, i. e. the movement is

taken out of the case and the

hands and dial are removed.

2. Cleaning of parts

With great care, a master watch-

maker totally disassembles the

movement. Then, the par ts are

thoroughly degreased and cleaned

with special cleaning liquids.

3. Visual inspection

The master watchmaker scruti-

nises every single movement part.

Depending on the model, this

may involve the examination of

several hundreds of parts. Com-

ponents that exhibit even the

slightest damage are replaced.

4. Reassembly of the movement

Then, the movement is reassembled

with great care. All bearings and

functional surfaces are now lubri-

cated with an oil dispenser, a tiny

After the rate accuracy of the watch

has been checked with a timingapparatus, it is adjusted in five

different positions. With minimal

shifts of weight, the balance wheel

is poised step by step to optimise

the duration of its oscillations.

6. A full check-up

All mechanisms of the completely

assembled movement, such as

the winding train, the outsize date,

the stop-seconds mechanism or

complications are checked for flaw-

less functionality and adjusted if

necessary.

7. The endurance test

This is followed by a multi-day

run-in phase on a watch winder

that simulates the motions of the

wrist. Subsequently, the master

watchmaker allows the watch to

run down; this is done to check

its power reserve.

8. The final inspection

After the movement has been

recased, the second multi-day

trial run takes place. During the

rigorous final inspection of the

watch, it is checked for visual

flawlessness, water resistance,

functional integrity, and, for alast time, rate accuracy.

Fineness

In the carat system, the quality or fineness of precious metals is expressed in carat (karat is the preferred spelling

in the USA). The European system, based on one thousand weight units, is also commonplace. The two systems correlate

as follows:

18-carat gold is equivalent to 750/000 gold,

21-carat gold is equivalent to 875/000 gold,

and platinum is 950/000 platinum.

There is a simple technical reason for the absence of pure gold and pure platinum in horology: both metals are too soft

for the production of watch and movement components. Gold and platinum are alloyed with other metals to significantly

increase their hardness. The different hues of pink and white gold are also achieved by alloying.

Bearing jewels

The reference to Rubine on the plates of Lange movements applies to friction- reducing, wear-resistant functional jewels

consisting of synthetically produced ruby for bearings, switching and detent elements, and the escapement. Because of

the greater homogeneity of the crystalline structure as opposed to natural ruby with otherwise virtually identical physical

and chemical properties, the use of synthetic ruby is very commonplace in watchmaking today. The English equivalent

of the German term Rubine is jewels.

Diamonds

At Lange, we have subjected all our purchases of diamonds to the System of Warranties since the scheme was introduced

in January 2003. We request a Statement of Warranty to be formalised on every diamond-related invoice we receive.

Lange engages in long-term relationships with suppliers who share our values.

leather used for our straps is sourced exclusively from alligator farms in the USA. Here, alligators are raised pursuant to legal

provisions under natural habitat conditions. Trade is also subject to stringent state regulations. The species protection

tag attached to the alligator leather strap of a new Lange watch bears a registration number that is checked by customs

officials when imported; it allows complete tracking to the manufacturer.
