Omega Seamaster Aqua Terra 150M 41.5mm steel on steel

OMEGA’s Seamaster Aqua Terra > 15,000 Gauss is the world’s first completely anti-magnetic timepiece. This watch features a slightly yellow lacquered black dial with a date window at 3 o’clock and a black and yellow seconds hand which matches the yellow numerals on the minute track.
The bezel is mounted on a 41.5 mm stainless steel case and is presented on a stainless steel bracelet. A scratch-resistant sapphire crystal protects this unique dial. A second scratch-resistant sapphire crystal on the caseback allows an unobstructed view of the anti-magnetic OMEGA Co-Axial calibre 8508 powering the timepiece.
