Crafted bridges, rapidly oscillating balance wheel, gearing and distinctive battle-axe shaped automatic winding rotor are all open to view. This allows the wearer to fully appreciate the art and craft that makes up HM3 and draws the viewer’s gaze inside the highly complex machine; a machine comprising more than 300 fine-finished, high-precision components.

Turning the watch over reveals the technical secret behind HM3’s inverted movement: two large high-tech ceramic bearings efficiently transmitting power up to the cones and date wheel.

Two styles are available in both red gold and white gold for $74,000 each.
