The Omega Speedmaster Reduced Date reference 3511.20.00 represents one of the standard
executions of the Speedmaster Reduced line introduced in 1988, the platform that
brought the Moonwatch aesthetic into a more wearable 39mm automatic-winding format
and remained in production until 2009. The 39mm stainless steel case features a 
fixed tachymeter bezel in black anodized aluminum and a domed sapphire crystal, 
the smaller footprint making the watch significantly more wearable than the 42mm
Professional Moonwatch while preserving the Speedmaster visual identity. The black
dial carries applied luminous indices, Omega’s signature broad-arrow hour hand, 
a date window at three o’clock, and a tri-compax chronograph layout with running
seconds at nine, 30-minute counter at twelve, and 12-hour counter at six. The Speedmaster
Reduced was offered with several caliber generations across its production run including
the 1140, 1141, 1143, and 3220, all built on modular automatic architecture pairing
an ETA base movement with a chronograph module. Water resistant to 30 meters, fitted
on a stainless steel bracelet with deployant clasp. The 3511.20.00 sits as one of
the standard catalog configurations of the Speedmaster Reduced line alongside the
silver-dial 3511.30.00 and reverse-panda 3511.50.00. Pre-owned condition.
