Omega Speedmaster Reduced 3510.50

Stainless Steel, Omega Speedmaster Reduced Automatic Chronograph Wristwatch, circa 1988 -2000

The Omega Speedmaster Reduced debuted in 1988 as a smaller, more accessible alternative to the Professional Moonwatch, responding to market demand for a Speedmaster that fit under shirt cuffs and suited smaller wrists. The reference 3510.50 maintained the iconic tri-register layout and tachymeter bezel of its larger sibling while introducing an automatic calibre based on the ETA 2890-A2, distinguishing it from the manual-winding Professional. Produced until the early 2000s, the Reduced developed its own following among collectors.
