Description

OMEGA’s sporty Seamaster collection is a tribute to the brand’s maritime legacy. This exquisite example of our renowned watchmaking pays homage to OMEGA’s dive watch heritage and our adventurous pioneering spirit.

This OMEGA Seamaster Diver 300M GMT Chronograph features a matt blue dial with 30-minute and 12-hour recorders and a small seconds sub-dial. There is a yellow GMT hand that matches the yellow 24-hour scale on the dial which makes it possible to keep track of time in a second time zone. The matt blue ceramic unidirectional rotating bezel is mounted on a 44 mm stainless steel case with a helium-escape valve.

The watch is presented on a stainless steel bracelet. This chronograph is powered by the OMEGA Co-Axial calibre 3603.

Stainless Steel

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.

Sapphire Crystal

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.
