The relationship between man and watch is as nuanced as the one between man and dog. Introducing man’s new best friend, Horological Machine N°10 ‘Bulldog’.

A rounded, compact body of titanium or red gold, coupled with a generous ration of sapphire crystal. Two prominent aluminium time-display “eyes”, rolling at anyone who dares look its way. A collar studded with projections that allow you to wind the mainspring or set the time. Stout but flexible “legs” that wrap firmly around your wrist. A massive jaw. And above all, a big heart beating steadily at 2.5Hz (18,000vph).

Just like the creature for which it is named, there’s more to HM10 Bulldog than meets the eye. Its hinged jaws open and shut according to the amount of wind left in its mainspring — a fully closed mouth tells you that “Bulldog” is wound down and ready for a nap. If you can clearly see the rows of shining teeth lining the jaws, get ready, because that means “Bulldog” is full of fight, charged up with a 45 hours of mainspring energy. This massive power-reserve indication has been carefully designed and calibrated to consume the least energy possible, allowing HM10 Bulldog to direct its considerable mainspring torque solely towards its suspended balance and its revolving hour and minute domes.

The manual-winding engine of HM10 Bulldog was designed and developed in-house, leveraging the best of MB&F’s technical expertise built up over the years; longtime members of the MB&F Tribe will recognise elements that hew closely to the horological lab’s best-loved creations. The large suspended balance that hovers just beneath the central dome of sapphire crystal was made possible by the various iterations of this mechanism in the Legacy Machine collection. The massive jaws that indicate the level of mainspring wind are a much-expanded demonstration of the power-reserve management that was first deployed in the 2014 LM1 Xia Hang. The paper-thin aluminium domes have their roots in the HM3 Frog and were refined in 2014’s HM6. Even the grillework design motif in the “ribs” set beneath the balance and in the tail-end of the body echoes the automotive-inspired HM8, HMX and HM5. Taken altogether, the message is clear: HM10 Bulldog is a highly bred machine.
