Omega Speedmaster Professional Moonwatch Jubilee Chronometer | 18K Yellow Gold

The Omega Speedmaster Professional Jubilee Chronometer Ref. 3694.50 is an exceptionally rare and luxurious interpretation of the legendary Moonwatch. Released in 1992 and limited to only 250 individually numbered examples, this special edition commemorated the 50th anniversary of Omega’s historic 27 CHRO C12 movement—the movement lineage that would later become the legendary Calibre 321.

Crafted from solid 18K yellow gold, the watch retains the familiar 42mm Speedmaster Professional case while offering a noticeably more elevated and distinctive presence. Its black dial features applied gold hour markers, matching gold-tone hands, three recessed chronograph registers, and the uncommon “Chronometer” designation beneath the Speedmaster Professional signature.

One of the defining features of the Ref. 3694.50 is its chronometer-certified Omega Calibre 864 manual-winding movement. Based on Omega’s renowned Moonwatch movement architecture, the Calibre 864 was specially finished, adjusted, and certified for accuracy. It can be viewed through the sapphire exhibition caseback, which also carries the watch’s individual limited-edition numbering.

Combining genuine Moonwatch heritage, precious-metal construction, chronometer certification, and an extremely limited production of only 250 pieces, the Ref. 3694.50 is one of the most collectible and seldom-seen gold Speedmaster Professional references.
