Omega Speedmaster Reduced Chronograph Watch, Automatic, 3510.50 - Stainless Steel


Item No. 5436ST

The Speedmaster Reduced showcased in today's offering is a prime original example of one of the automatic watches in the Speedmaster line. It remains at very high condition levels - about a 9.5 out of 10, and the luminous has toned just enough to give the watch a bit of a classic look.

It has just been freshly fully serviced and it is 100% Omega down to the crystal and waterproofing seal (a $495 value).

Accompanying the watch are its original boxes.

Included with the purchase is a one-year C.O.T. warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

Omega Speedmaster:
In 1957, Omega unveiled a chronograph that was a true technological marvel, the Speedmaster. Its incredible durability and accuracy would not only win it accolades around the world and the distinction of being the first watch to be worn on the moon, it would accomplish something far more important, guiding the crew of Apollo 13 safely back home after their malfunctioning electronic systems had shut down.
