Travel Without Limits

Main Materials
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.
Aluminium
Aluminium has the advantage of being a truly lightweight material used for decorative components. Through anodisation, it offers an extensive range of colours for the creation of eye-catching watch parts such as bezel rings, applied elements on the dial, and hands. In particular, OMEGA’s special anodisation process has achieved aluminium bezel rings that are nearly double as hard as regular versions, therefore making them more resistant to outer damage.
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.
Movement
Automatic
Self-winding movement, resistant to magnetic fields reaching 15,000 gauss. Free sprung-balance with silicon balance spring, automatic winding in both directions. Rhodium plated finish with Geneva waves in arabesque.
DESCRIPTION
This 43 mm Worldtimer model includes a polished case in stainless steel which is integrated with the structured blue rubber strap via a solid polished link.
The exterior section of the dial is sun-brushed blue and includes vertical teak stripes and a circle of global destinations printed in red (GMT), silvery (+1h in summer) and blue (places without daylight savings).
The centre of the dial contains a 24-hour glass ring, with light blue to indicate daytime and dark blue to indicate night. The vision of Earth is created on a grade. This has been laser-ablated to create the blue ocean, leaving a relief of the continents. The contrasting colours of the Earth’s surface are obtained naturally by the laser’s chemical reaction.
FEATURES
Antimagnetic, Date, Unidirectional rotating bezel.
