Omega Speedmaster Triple Date 3521.30 – The Complication You Didn’t Know You Needed

Blending the legendary DNA of the Speedmaster with the sophistication of a full calendar, the Omega Speedmaster Triple Date (Ref. 3521.30.00) delivers technical complexity in a beautifully balanced 39mm case — and does it with effortless style.

Housed in brushed and polished stainless steel, the case offers timeless proportions that wear comfortably on the wrist. The silver dial is sleek and functional, featuring day and month apertures at 12 o’clock, a 24-hour indicator at 9, and a discreet date window integrated within the 12-hour chronograph sub-dial at 6. A fixed tachymeter bezel surrounds the dial, maintaining the sporty heritage of the Speedmaster line, while leaf-style hands and applied hour markers add a refined touch.

At its core is the Omega Calibre 1151 — a self-winding movement based on the proven Valjoux 7751. It powers the chronograph and full calendar with precision and reliability, making this watch as practical as it is striking.
