Description
The Omega Speedmaster Day-Date (Ref. 3523.80) combines the complex “Triple Date” layout with a brilliant sunburst blue dial. It packs a staggering amount of horological utility into a highly wearable 39mm stainless steel case: a full 12-hour chronograph, a pointer-date track around the dial perimeter, day and month apertures at 12 o’clock, and a 24-hour day/night indicator at 9 o’clock.
