The Omega Seamaster Aqua Terra Ref. 2503.80 is a refined first-generation Aqua Terra that combines sporty durability with a clean, understated design. It features a 39.2mm stainless steel case, blue dial with applied hour markers, luminous arrow-style hands, a date window at 3 o’clock, sapphire crystal, transparent caseback, and stainless steel bracelet. Its balanced proportions make it equally suitable for everyday and formal wear.

Powered by the automatic Omega Calibre 2500, the watch features Omega’s Co-Axial escapement, chronometer-certified performance, and an approximately 48-hour power reserve. This example includes all three original Omega cards—the International Warranty Card, Chronometer Certificate Card, and Pictograms Card—adding completeness and collector appeal without describing it as a full set unless the original box and additional accessories are also included.
