Offered here is the Omega Seamaster Aqua Terra reference 231.13.42.21.03.001, a properly executed luxury sports watch built the old-fashioned way: strong casework, real water resistance, and a movement made for daily use not display-case living. The blue teak dial delivers the Aqua Terra’s signature vertical patterning, shifting from slate to deep marine tones depending on the light, with crisp applied markers and a balanced date window at 3. Inside is Omega’s Co-Axial Caliber 8500, visible through the sapphire caseback and paired with serious real-world durability this reference is marked for 15,000 gauss anti-magnetic resistance, an advantage that matters in modern life (phones, magnets, laptops… you know the usual suspects). Add 150m / 500ft water resistance, and you have a watch that can actually keep up without pretending to be a submarine. Condition is excellent, showing only light surface wear consistent with careful ownership nothing distracting, nothing hidden. The set is correct and complete: double box, warranty card dated 2024, pictogram card, card holder, manual, and an additional OEM leather strap a strong package for an end-user or collector who values completeness.
