CALIBRE NUMBERING

Subject

• The above-mentioned Omega movements have received quality enhancements: changing from

the older gilt or simple rhodium-plated versions to high-grade rhodium-plated versions. These

modifications were started in 1995 on the mechanical movements.

• On the new versions, the basic calibre (ETA) is no longer indicated.

Decision

• A new codification of the calibres concerned (see list).

Notes

• The bridges, main plates and electronic circuits are specific to a particular calibre and must not be

used on the other movements. Only the basic components are interchangeable.

• The existing technical documentation remains valid.
