Omega has always been driven by a pioneering spirit; in fact, no watch company in the world holds more records for accuracy. Their watches have been the timepiece of choice for some of history’s greatest explorers—from deep-sea divers to astronauts. 

This handsome Seamaster celebrates the legacy of a unique Omega timepiece going back to 1957: the Railmaster, which was built specifically for railroad employees or others who found themselves working near electrical fields. True to that spirit, today’s Railmaster timepieces are still resistant to magnetic fields of 15,000 gauss. Other unique railroad features here can be found on the brushed “black jeans” dial. 

Its stainless steel case measures 40 mm in diameter and sports a screw-down winding crown, 150 m / 15 atm water resistance, and domed scratch-resistant sapphire crystal. 

As a self-winding automatic timepiece and master chronometer, it delivers certified accuracy that you can depend upon, as well as a 55-hour power reserve. It is driven by the Omega co-axial 8806 caliber. 

Brushed stainless steel hands and recessed hour markers are filled with beige SuperLuminova for easy viewing in low light. In addition, there is also an attractive beige center seconds hand. The “black jeans” dial is clean in design and offers Arabic numerals at 12, 3, 6, and 9 as well as a minute track and hour markers designed to draw the eye inward. 

Standout feature(s): Master chronometer accuracy; resistant to magnetic fields of 15,000 gauss; brushed dial.
