Omega Speedmaster Reduced Day Date Chronograph 39mm 3523.30.00 (1999)

The Omega Speedmaster Reduced Day-Date Chronograph ref. 3523.30.00 (1999 era) is a distinguished and versatile take on Omega’s iconic Speedmaster lineage, combining classic chronograph sportiness with full calendar functionality. Housed in a 39 mm stainless steel case, this model features a sophisticated silver sunburst dial with multiple chronograph sub-dials, a fixed tachymeter scale, and a triple calendar display — including day and month windows at 12 o’clock and a date shown via a central crescent-tipped hand around the outer edge of the dial. Powered by the automatic Omega Calibre 1151 (based on the reliable Valjoux 7751), it delivers robust daily performance with a rich mechanical feel. A stainless steel bracelet enhances its balanced, rugged-yet-elegant character, making the 3523.30.00 both collectible and practical for everyday wear.
