Rare 18 carat yellow gold Omega chrono-tachymetre pocket watch

A brief history on the Omega 18″ P CHRO movement.

Introduced by Omega in 1906, this movement was slimmer that the earlier 19″ CHRO (7.15mm thick compared to 9.25mm) and was subsequently also used to power Omega’s first chronograph wrist watches.

This spectacular movement features a centre chronograph seconds to 1/5th of a second, and either a 15 or 30 minute counter (in our case a 30 minute counter). Called a chrono-tachymetre, this is due to a tachymeter able to measure speed, and a chronometer able to measure time, and as this movement can do both, this term is used.

The dial is not only signed “Omega”, but also signed “Cadran Breveté S.G.D.G.” which is the abbreviation of “Sans garantie du gouvernement” which translates to “Without government guarantee”. This was the term used under French law since 1844 and designates that it was assigned for the French market and colonies only.
