This 38 mm Aqua Terra, with a symmetrical case in fully polished stainless steel, has a polished and brushed bracelet formed by beautifully rounded links.

The sun-brushed dial, in OMEGA’s own Summer Blue, is PVD-treated and varnished with a gradient finish to reflect the watch’s level of water resistance. It has rhodium-plated hands and sailboat hull indexes filled with a unique light blue Super-LumiNova and a matching blue date window indicator at 6 o’clock.

Turning the watch over reveals a stamped commemorative Seamaster logo depicting a trident-bearing Poseidon and two seahorses: OMEGA’s 1956 original and the brand’s current design. Behind which sits OMEGA’s Co-Axial Master Chronometer calibre 8800, certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).
