Omega Cosmic Moonphase from 1947 Caliber 381 TOP

€0,00 Sold out
Tax included.

The Cosmic collection was introduced in 1947 and Omega had it in production until 1956. At the time it was one of the most exclusive watches the brand could offer. The Omega Cosmic watches came in two sizes (34-35mm and 37.5mm) in four different case materials.

Some call it “moon phase”, others write “moonphase”. Since Omega uses the latter term, I’ll go with that too. Moonphase is a complication that is fairly useless nowadays. However, it connects us to the very beginning of time measuring. The cycle of the Moon is approximately 29.5 days.

Omega only used one type of movement in their Cosmic watches. Omega calls it the caliber 381 in their database. However, that movement only got its name changed to caliber 381 around 1948 (some say 1949). Beforehand it was called the 27 DL (PC AM)

This nice example date to the year 1947 , still in really good condition, the watch has been polished before but the case still in sharp condition.

The dial is in 8 to 10 condtion as well.
