Details & Specifications
Description:
The Omega Speedmaster Automatic "Reduced" (reference 3510.50) brings the iconic Speedmaster chronograph look to a more compact, self-winding form. Introduced in 1988, it earned its "Reduced" nickname from its smaller 39 mm case, compared with the 42 mm of the manual-winding Speedmaster Professional. Crafted from stainless steel with twisted lugs, it offers a balanced, easy-wearing wrist presence. The black dial, featuring luminous baton hour markers and a tri-compax layout with a 30-minute counter at 9 o'clock, small seconds at 3 o'clock and a 12-hour counter at 6 o'clock, is powered by an automatic chronograph movement based on the ETA 2890-2 with a Dubois Dépraz chronograph module, offering the convenience of automatic winding.
With its fixed black tachymetre bezel, hesalite crystal and stainless steel bracelet with folding clasp, this Speedmaster bridges Omega's spaceflight heritage with everyday usability. This watch remains a versatile classic—equally at home as a daily wear or as a first step into Speedmaster ownership.
This piece presents in excellent condition. Watch only.
