HM10 Bulldog may be intimidating with its features but there’s more to it than meets the eye.
March 28, 2020: MB&F creations have always attracted a highly loyal audience and HM10 Bulldog returns the favour in spades. The new horological machine N°10 bulldog is a rounded, compact body of titanium or red gold, coupled with a generous amount of sapphire crystal. It is full of fight, charged up with 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, 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.
Despite its outsize personality — measuring 45mm across, 54mm from nose to tail and with a maximum height of 24mm — HM10 Bulldog is surprisingly wearable. Its sprung strap attachment “legs” allow the body to fit closely around the wrist, with the calf-leather strap as robust as any well-made leash — fastened with either a folding buckle or Velcro system.
Available in both titanium and a combination of titanium and red gold, HM10 Bulldog is assembled with highly distilled expertise in micro-mechanical engineering. MB&F Horological Machine N°10 ‘Bulldog’ is available in two launch editions: grade 5 titanium body with blue “eyes”, and 18k red-gold and titanium body with black eyes.
