Already in 2015, the GMT Black paved the way for the GMT Sport. Building on this foundation, Robert Greubel and Stephen Forsey have invented and now present the result, a lightweight and ultra-strong, profiled titanium case with ovoid bezel and integrated lugs to showcase the new movement. Water resistant to 100 meters, the new GMT Sport stands out as their most sport oriented timepiece to date. The movement was constructed from scratch – from the suspended arched bridge for the hours and minutes display, to the unique showcase of the Tourbillon 24 Secondes and the universal time display with three dimensional globe.
