About
The Speedmaster is a watch that seldom needs introduction. Its rich history, from automotive racing to the US flight program and NASA, has captivated multiple generations of watch enthusiasts.
Sometimes referred to as the “Triple Date”, the 3521.30 features the same robust design as other automatic Speedmaster models of the era, with a 39mm case size that makes for a comfortable wear for most any wrist. What sets this model apart is the addition of a triple calendar function, with day, date, and month indicators, as well as a 24 hour indicator on the left side register. All of this information is arranged tastefully on the dial, while this particular version with a silver dial and steel bezel combo helps to maintain its understated aesthetic.
This example has just been given a full overhaul by Omega, and comes with their 2 year mechanical warranty.
