BALL Engineer III GM9100C-S2C-GY Automatic Grey Watch | 41mm Stainless Steel

Endurance 1917 Series: built to endure the unendurable. As his leadership, courage and optimism continue to captivate explorers around the world, BALL Watch Company is proud to introduce its second series inspired by the legacy of Sir Ernest Shackleton’s Trans-Antarctic Expedition.

The 41mm Engineer III Endurance 1917 GMT features BALL’s new Manufacture GMT Caliber RRM7337-C, a true GMT chronometer wrapped in a 904L stainless steel case and shining with micro gas tube luminosity. The self-powered H3 micro gas tubes provide extreme readability and trusted reliability in all pursuits. This GMT timepiece possesses gas tubes also on the 24-hour inner.

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 changes the local 12-hour hand by using the crown. The GMT hand is completely unaffected while the seconds hand continues to move, for an 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 the local time zone. The movement and all its smart functionality are shielded by 1,000 Gauss anti-magnetic protective technology.
