Built to endure the unendurable

The 41mm Engineer III Endurance 1917 GMT features our Manufacture GMT Caliber RRM7337-C – a true GMT chronometer – wrapped in a 904L stainless steel case and shining with micro gas tube luminosity. The 24-hour inner bezel features our revolutionary tubes for reading the home time in total darkness. The all-around glow extends to all four hands – even the GMT hand – and around the dial with fully illuminated hour markers.

Fully automatic and highly accurate, the BALL Manufacture GMT Caliber RRM7337-C is an officially certified chronometer. With true GMT status, its quick-set functionality lets you easily change the local 12-hour hand by using the crown. The GMT hand is completely unaffected while the seconds hands continues to move – giving you uninterrupted precision. As the 12-hour hand jumps in one-hour increments, the date wheel moves in perfect synchronization and always indicates the correct date of your local time zone. The movement and all its smart functionality are shielded by 1,000 Gauss anti-magnetic protective technology.
