A rounded, compact body of titanium or red gold. 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. 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. 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.
