HANDS-ON : A vintage Omega Cosmic

OmegaCosmic1

In 1947 Omega introduced their first calendar complication watch, the Cosmic Moonphase triple date calendar. It was produced, during the course of its existence, in both square and round cases, and with a variety of metals/ dial colours. It was the brand’s first watch that displayed the time and the date with hands and day, month and moon phase in windows. The square models were introduced in 1951, and it is one of these, in 14k yellow gold, that is the subject of today’s post.

This rare original Cosmic, which even has its box, has tear-drop lugs, domed sapphire crystal, alpha-styled hands. The dial is silver with applied gilt indices, outer minute divisions, a sub dial for the seconds which ‘overlaps’ with the moonphase indicator, windows showing the day of the week and month, and an ring with the days of the month in painted blue Arabic numerals. The movement is the manual Cal. 381, with 17 jewels, straight-line lever escapement, monometallic balance, shock absorber, self-compensating flat balance spring, index regulator. It is 33mm x 33mm in size, very small by today’s standards, with a thickness 12.8 mm.

Such was the significance of this piece for Omega that they re-issued a limited edition (1951) modern version of the square Cosmic in 2002 as part of the Omega Museum Collection. The modern version was of the square model, retaining the original design features down to the lugs, but with a water resistance of 50m. A manual winding movement was replaced with an automatic Calibre 2601 movement with a 72 hour power reserve.

  2. I’ve got a round one, I never knew they were known as “Cosmic”, I’ve always referred to mine as a “triple date moon”. Haven’t worn it for some months, might have to give it a few days wrist time.
