About This Watch

The Omega Speedmaster Date Ref. 3511.50 is a classic and highly versatile chronograph that blends the iconic Speedmaster heritage with a refined and balanced design. With its 39mm case, this model offers ideal proportions, making it comfortable for everyday wear while still delivering the sporty presence expected from the Speedmaster line. This reference features a striking “tuxedo” dial configuration, combining a black base with contrasting white subdials. The layout includes three chronograph subdials, applied markers, and a date display at 3 o’clock, creating a sharp and highly legible design. The contrast between the black and white elements gives the watch a more dynamic and dressy appearance compared to standard monochrome Speedmasters. The dial is enhanced by luminous hands and markers, while the tachymeter bezel reinforces the Speedmaster’s racing DNA. Compared to larger and thicker modern Speedmaster models, the 3511.50 offers a more classic and wearable profile, appealing to those who prefer traditional sizing with a distinctive dial variation. 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 provides consistent performance along with approximately 44 hours of power reserve.
