The Omega Speedmaster ref. 3573.50 is a collector-favorite interpretation of the legendary Speedmaster Professional, combining the classic Moonwatch design with the added appeal of a sapphire crystal and exhibition caseback. The iconic black dial, three-register chronograph layout, and unmistakable Speedmaster case make this a timeless modern classic with strong collector appeal.

This example is a full complete set with open-date card and presents in excellent condition. It features the desirable sapphire “sandwich” configuration, offering a view of the beautifully finished movement through the display caseback. The original bracelet is fully linked with no stretch, making this a particularly complete and well-preserved example.

A fantastic Speedmaster for the collector who wants the classic Moonwatch aesthetic with the added refinement of sapphire crystal and a display back — a standout example of the ref. 3573.50.
