Omega Speedmaster "Triple Date/Calendar Moonphase" Ref. 3331.20.00

Omega Speedmaster "Triple Date/Calendar Moonphase" Ref. 3331.20.00 with the Automatic Omega 1150 calibre movement. 54 Hour power reserve.

Case diameter 38mm excluding crown, 40mm including. This measures 45mm lug to lug with a 18mm lug width and 12mm thickness.

This is on an OEM Omega non Two-Tone bracelet with all genuine links. Since this photo I purchased two additional links so the watch will now accommodate a wrist size approximately up to 7-5/8".

Part of the international collection launched in 1990 this revived the granddaddy of this series, the Omega Triple Calendar cosmic but with a Speedmaster flare. If you're like me and often forget what day of the month it is or what month or curious a out the lunar cycle this watch has you covered.

The lovely 18k yellow gold accents such as the solid gold bezel or the crown and pushers really make this thing pop and the gold indices on the white dial is a surreal look.

The serial dates this watch to the mid-90s.
