Horological Machine N°10 Bulldog

BHD 54,200.000
by MB&F
Description

The HM10 Bulldog doesn’t sit quietly on the wrist — it growls. Designed as a compact yet powerful Horological Machine, it features a sculptural titanium case, domed time displays, and articulated “jaws” that visually track the mainspring’s energy reserve.

Hours and minutes are displayed via rotating aluminum domes — hours on the left, minutes on the right — while a bespoke 14 mm flying balance wheel floats above the dial like a mechanical heartbeat. As power runs down, the Bulldog’s jaws slowly close, reaching full shut at the end of its 45-hour reserve.

Engineered and manufactured in Switzerland by MB&F, the HM10 is finished with an unmistakable warning engraved on its body: “Forget the dog, beware of the owner.” Subtlety was never the point.
