The Omega Speedmaster Reduced Racing reference 3510.12.00 is the yellow-dial chapter of Omega's original Michael Schumacher Racing trio introduced in the mid-1990s, the trilogy consisting of bold yellow, red, and blue lacquered dials that paid tribute to the German driver's career and stand today as some of the more characterful Speedmasters of their era. The 39mm stainless steel case carries a fixed tachymeter bezel in black anodized aluminum and a sapphire crystal, the smaller footprint making the watch more wearable than the 42mm Professional Moonwatch while preserving the Speedmaster visual identity. The yellow lacquered dial features a racing-inspired minute track, contrasting black sub-registers at three, six, and nine o'clock, a date window at three, and Omega's signature broad-arrow hour hand. The dial transitions from light lemon yellow to deeper ochre depending on light angle, lending the watch a distinctive vintage character. Powered by the Omega Caliber 1143, a modular automatic chronograph based on ETA 2892-A2 architecture with the Dubois Depraz 2020 chronograph module. The reference was introduced in 1996 and produced until 2000. The 3510.12.00 remains one of the more characterful Speedmaster Reduced configurations and a frequent collector entry point into 1990s Omega chronographs. Pre-owned condition.
