Product Details
The military-inspired dial layout uses applied numerals and indexes, with high-grade
Super-LumiNnova, to ensure utmost legibility, with deft twists that characterise
Bremont’s detail-oriented design. The GMT hand is tipped with Bremont’s signature
red arrow, read against a 24-hour day/night ring, while the running seconds display,
denoted by a rotating tri-blade propeller motif, was inspired by a Bremont military
project. This is also the first time that Bremont’s Wayfinder logo has appeared at
3 o’clock on a dial.
The Altitude Chronograph GMT is available comes with either a black dial, or in
brushed silver with contrast finish for the chronograph subdials. It is available on
the quick-release Altitude bracelet, on a nubuck leather strap or on a NATO strap.
