Omega Constellation 2988SC caliber 504, from the year 1957

During the 106”50-60s, Omega has produced some of the most beautifully designed watches with special dials. Recently, my interest with Omega has started to come back. This is an Omega Constellation with hooded lugs and pie pan dial with arrowheads markers. 冚耳, 八卦面，烏蠅字。

Calibre 504 was the first date model to appear in the 500 series Constellation range, believed to have been released just after, or concurrently with, the calibre 502 non-chronometer date model. Only 25,000 calibre 504s were produced, adding to their collectibility, and, as such, the calibre often has a special place in the collections of Constellation aficionados. The date setting is not of the quick-set variety and it is quite a laborious task to set the date if you take the watch out for irregular walks on different days of the month. Coupled with its comparative rarity, it represents good historical and investment value.

Calibre 504 featured a number of very attractive dials with arrow-head, faceted and onyx inlaid markers. The first dated version of the Grand Luxe was also powered by a calibre 504 and the gold dial with gold and onyx markers is a feast for the eyes.
