Seamaster Aqua Terra

The Omega Seamaster Aqua Terra 150M >15,000 Gauss, reference 231.10.42.21.01.002, is a technically groundbreaking timepiece that marked a major milestone in anti-magnetic watchmaking. Designed to withstand magnetic fields exceeding 15,000 gauss without the need for a soft iron inner case, this certified pre-owned luxury watch combines innovation with the elegant versatility of the Aqua Terra collection. It is presented in very good condition and supplied with its original box and papers.

The watch features a 41.5 mm stainless steel case paired with a matching stainless steel bracelet, offering balanced proportions and a robust yet refined wrist presence. The black dial, inspired by the “teak concept” pattern associated with the Aqua Terra line, is accented by distinctive yellow details that highlight its anti-magnetic identity. Applied hour markers and luminous hands ensure excellent legibility, while a date window at 3 o’clock provides everyday practicality.

Powering the watch is the Omega Co-Axial Calibre 8508, an in-house automatic movement specifically engineered to resist magnetic fields greater than 15,000 gauss. This chronometer-certified calibre features the Co-Axial escapement and twin barrels, delivering a power reserve of approximately 60 hours and exceptional long-term reliability.

In very good overall condition, the case and bracelet show only light signs of wear consistent with careful ownership. Accompanied by its original box and papers, this pre-owned luxury watch represents an outstanding opportunity to acquire the Omega Seamaster Aqua Terra >15,000 Gauss 231.10.42.21.01.002, combining advanced anti-magnetic technology, in-house mechanical excellence, and versatile design.
