Omega Speedmaster Reduced 3510.50.00 Stainless Steel

The Omega Speedmaster Reduced reference 3510.50.00 represents the long-running base configuration of the Speedmaster Reduced line introduced in 1988, the platform that brought the Moonwatch aesthetic into a more wearable 39mm automatic format and remained in production until 2009. The 39mm stainless steel case carries a fixed tachymeter bezel in black anodized aluminum and a sapphire crystal, the smaller footprint making the watch significantly more wearable than the 42mm Professional while preserving the Speedmaster visual identity. The black dial features applied luminous indices, Omega’s signature broad-arrow hour hand, and the tri-compax chronograph layout with running seconds at nine, 30-minute counter at twelve, and 12-hour counter at six. Across its two-decade production run, the reference 3510.50.00 was offered with several caliber generations including the Caliber 1140 (1988), 1141 (1996), 1143 (1997), and finally 3220 (2003), all built on modular automatic architecture pairing an ETA base with a chronograph module. Water resistant to 50 meters, fitted on a stainless steel bracelet with deployant clasp. The 3510.50.00 spans the longest production window of any Speedmaster Reduced reference, making it the canonical example of the platform. Pre-owned condition.
