Royal Oak Concept Split Second Chronograph GMT Large Date 43 mm

The Royal Oak Concept collection, which debuted in 2002, gets its first split-seconds flyback chronograph. The movement is the 4407 automatic calibre, which is visible through the sapphire back of the 43mm titanium case, whose three-dimensional forms play with textures, relief and light. This new movement powers a split-seconds flyback chronograph with a 30-minute counter, a GMT function and a large date. The GMT display at 3 o’clock is based on a disc and a hand turning at different speeds: the hour hand makes a revolution in 12 hours, while the day/night display disc, one half black, one half white, completes its rotation in 24 hours. Also new to the collection is the interchangeable strap, in black rubber.
