About This Watch

The Omega Speedmaster Date Ref. 3511.80 is a distinctive and versatile chronograph that blends the iconic Speedmaster DNA with a more refined and colorful aesthetic. With its 39mm case, this model offers a balanced wrist presence that stays true to the classic proportions of earlier Speedmaster designs while remaining highly wearable for everyday use. This reference features a rich blue dial with a traditional chronograph layout, including three subdials, applied markers, and a date display at 3 o’clock. The blue tone adds a unique personality to the watch, standing out from the more common black dial Speedmasters while still maintaining excellent legibility and contrast. The dial is complemented by luminous hands and markers, while the tachymeter bezel preserves the Speedmaster’s racing heritage. Compared to larger and thicker modern Speedmaster models, the 3511.80 feels more compact and classic, making it a great option for those who appreciate vintage proportions with a bit of added color. Inside, it is powered by the Omega Calibre 1152 automatic chronograph movement, based on the reliable Valjoux 7750 architecture. Known for its durability and ease of service, this movement delivers consistent performance along with approximately 44 hours of power reserve.
