Today's offering showcases this beautiful and complicated Certified Pre-Owned automatic Speedmaster, ref. 3523.30.00. Besides the chronograph the watch also possesses a triple date calendar and twenty-four hour time indication.

Its case and bracelet both carry a traditional speedy look, although the bezel is of the sleeker steel embossed variety. The silver dial is beautiful.

It is 100% Omega down to the waterproofing seal and presents as in gorgeous condition - a 9.7 or 9.8 out of 10. On the wrist it presents as perfect mint. The case back has very slight remnants of wear from the bracelet contacting it. Only with close inspection does the bracelet show signs of having been polished. The bracelet shows virtually no stretch - it's nearly as tight as new.

The movement is very clean. Photos of the inside available upon request. We have timed it in five chronometer positions, and it continues to keep time close to on par with a new Speedy maintaining chronometer grade accuracy in four of the five testing positions.

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

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.
