Description

The original OMEGA Railmaster of 1957 was a practical yet elegant anti-magnetic watch designed for railway staff or anyone who worked close to electrical fields. Today, that industrial spirit and innovation has been updated for a modern collection.

In this denim-inspired model, the 40 mm symmetrical case is made from stainless steel with a wave-edged design featured on the back. The vertically brushed “blue jeans” dial includes brushed stainless steel hands and recessed hour-markers which are all filled with light grey Super-LumiNova. There is also a beige central seconds hand and transferred “Railmaster” indication which delivers a classic touch.

The watch has a blue denim and leather NATO strap as well as an oriented caseback featuring a NAIAD LOCK design to keep the wording in position.  The watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8806, making it resistant to magnetic fields of 15,000 gauss.

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.

A new look for your watch

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.

The advantages
of this watch

Behind the elegance of every Master Chronometer timepiece is the highest level of testing: 8 tests over 10 days, to ensure superior precision and anti‑magnetic resistance. We’ve raised our standards. You can too.
