The New OMEGA Seamaster Aqua Terra 15000 gauss anti magnetic Watch

The OMEGA 8508 mechanical movement is introduced in the Seamaster Aqua Terra 15,000 gauss, a 41.50 mm stainless steel Co-Axial chronometer presented on either a matching bracelet or a brown leather strap. It has a slightly yellowed lacquered black dial, sun-brushed from the centre and decorated with the distinctive vertical lines that define OMEGA's popular Aqua Terra collection. The yellow transferred legend, "15'000 GAUSS" identifies the watch as a very special timepiece.

One of the most dramatic technological innovations in recent memory is the OMEGA Co-Axial caliber 8508. It is resistant to magnetic fields greater than 1.5 tesla (15,000 gauss), far exceeding the levels of magnetic resistance achieved by any previous watch movement and solving a problem that has challenged watchmakers for many decades.

The technology developed by a team of ETA, ASULAB, Nivarox FAR and OMEGA Engineers led to the first prototype of the movement, which has been fitted in an OMEGA Seamaster Aqua Terra. Unlike other efforts to combat the effects of magnetism, the OMEGA movement does not rely on a protective container inside the watchcase but on the use of selected non-ferrous materials in the movement itself. Several patents are pending for the new movement. Even after exposure to a magnetic field greater than 15,000 gauss, the movement still performs at a chronometric level as defined by COSC.
