Omega Speedmaster Reduced | Rare Blue Mother of Pearl Dial | Ref. 3502.73 I

The Omega Speedmaster Reduced Ref. 3502.73 is one of the more unique and visually striking Speedmaster variations, featuring a rare blue mother-of-pearl dial that changes beautifully depending on the lighting. The dial can shift between blue, silver, grey, and darker tones, giving the watch a much more dynamic presence than a standard black dial Speedmaster. This reference is known for its polished steel tachymeter bezel, lumed Arabic numerals, and automatic chronograph layout.

At 39mm, the watch has the classic Speedmaster feel in a more wearable size, making it easy to enjoy daily while still standing out on the wrist. What makes this example especially appealing is the unpolished condition, preserving the original case shape and character. For collectors, that matters because it keeps the watch feeling honest and original rather than overly refinished.

Powered by the Omega Calibre 3220 automatic chronograph movement, the 3502.73 offers the convenience of self-winding with the familiar Speedmaster chronograph experience. The mother-of-pearl dial is really the star here — rare, expressive, and far more memorable than most Speedmaster Reduced models.

Condition

Please note the bezel has a small ding near the bottom, which is hardly noticeable during normal wear and does not affect functionality or overall presentation.
