Pre-owned Omega Seamaster Aqua Terra 150M ref 231.10.42.21.01.002 (2015) is more than a sleek daily driver. It’s a quiet revolution on the wrist. This Omega was the first fully anti-magnetic wristwatch ever produced, thanks to the Omega Co-Axial caliber 8508 tucked inside the case. It shrugs off magnetic fields up to 15,000 gauss without a soft-iron cage, marking a turning point in modern watchmaking. The 41.5mm stainless steel case features a black lacquered dial accented with bright yellow elements, an apparent homage to hazard stripes and scientific instruments. The yellow-tipped seconds hand and matching minute track numerals give it a sporty yet tech-forward feel. Lastly, a date window rests at 3 o’clock, while a sapphire crystal on both sides provides the wearer with a clear view of the striped dial and the groundbreaking movement inside.
