The implausible has finally happened: The Swiss watch industry's enfant terrible Richard Mille has created a round watch. Famous for engineering what he calls a ‘rupture’ with classical watchmaking, Richard Mille turns to functionality for his brand’s first-ever diver’s watch.

This is, in fact, the reason for the round case: to attain water resistance of 300 meters, the round shape is the best. From luminous markers to unidirectional bezel, this watch meets all the professional requirements of a diving watch.

Nevertheless, the 18-ct red gold or white gold and titanium case is a complex tripartite affair and holds a movement that boasts many technical breakthroughs.

At 50.7mm in diameter, this is very much a contemporary watch. Among the uniquely Richard Mille touches are the torque screws on the case that enable precise control and distribution of pressure around the case and a bezel screwed to the case that enable precise adjustment of the bezel’s tension.

The presence of all the screws makes the water resistance rating even more remarkable. Complications wise, the watch features a tourbillon and a chronograph (with column wheel in titanium) on a movement based on the RM 008 carbon nanofibre calibre.
