Aqua Terra 150M Seamaster Steel Master Chronometer 220.10.41.21.03.005

This 41 mm Aqua Terra, with a symmetrical case in polished and brushed stainless steel, has a matching steel bracelet. The teak pattern dial, in OMEGA’s own Summer Blue, is sun-brushed, PVD-treated, and varnished with a gradient finish to reflect the watch’s level of water resistance. It has rhodium-plated hands and 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 8900, certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).
