Omega Speedmaster Triple Calendar Moonphase Two Tone | Ref. 3336.20

The Omega Speedmaster Ref. 3336.20 is a distinctive neo-vintage variation of the Speedmaster, combining the collection’s motorsport-inspired chronograph design with an elegant two-tone configuration and an impressive array of calendar complications. Housed in a stainless steel case measuring approximately 39mm, this reference features a white dial, 18k yellow-gold tachymeter bezel, sapphire crystal, and a combination of stainless steel and yellow-gold accents. Powering the watch is Omega’s Calibre 1150 automatic chronograph movement.

The appeal of the Ref. 3336.20 lies in its combination of classic Speedmaster styling and extensive functionality. The white dial incorporates chronograph registers, day and month indications, a date display, and a moonphase complication, while gold-tone hands, markers, and bezel details give the watch a more refined appearance than the traditional all-steel Speedmaster. Its compact 39mm proportions and automatic movement make it highly wearable, while the triple-calendar moonphase configuration gives the reference a distinctive character within the broader Speedmaster collection.
