Omega Speedmaster Reduced 39mm Stainless Steel Blue Tachymeter Bezel Date

The Omega Speedmaster Reduced reference 3510.51 represents a more accessible interpretation of the legendary Moonwatch, scaled to a wearable 39mm case diameter. Introduced in 1988, the Reduced line brought automatic winding and compact proportions to the Speedmaster collection while maintaining the iconic chronograph functionality. The 3510.51 variant features a distinctive blue aluminum tachymeter bezel insert, creating striking visual contrast against the black dial and stainless steel case.

The black dial showcases the classic tri-compax chronograph layout with three subdials: a 30-minute counter at 3 o'clock, running seconds at 9 o'clock, and 12-hour counter at 6 o'clock. Applied baton hour markers and luminous hands ensure excellent legibility. The blue tachymeter bezel, calibrated to 500 units per hour, provides racing-inspired functionality. The hesalite crystal maintains authenticity to vintage Speedmaster tradition, while the date window at 3 o'clock adds practical everyday utility absent from the Professional Moonwatch.

Inside beats Omega Caliber 1140, based on the robust ETA 2892-A2 base with Dubois-Dépraz 2020 chronograph module. This self-winding mechanical movement operates at 28,800 vibrations per hour with approximately 40 hours power reserve. The piggyback module construction achieves automatic winding while maintaining the Speedmaster's essential chronograph character. The integrated stainless steel bracelet with polished center links and brushed outer links provides comfortable wear with folding clasp. Water resistant to 30 metres, the Speedmaster Reduced prioritizes style and heritage over dive capability. Discontinued in the early 2000s, the 3510.51 has become increasingly collectible.
