Seamaster Aqua Terra 150M Co‑Axial Chronometer 41.5 mm
> 15,000 gauss
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.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

Stainless steel is certainly the most conventional of watchmaking materials for outer craftsmanship, and offers beauty, strength and affordability. OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
Your watch and strap should go together perfectly, but that doesn't mean you can't experiment with different combinations. Why not mix things up and see what happens? You may discover a look that's as individual as you are.
