Our Take

It seems like with every new MB&F release, Max and friends continue to push the envelope of creativity. Together, they’ve run the gambit of watch designs, drawing inspiration from jellyfish, frogs, vintage automotive. Adding to that list, the release of the HM10 continues to walk the path of bio-inspired designs with the timepiece being called the Bulldog.

The tenth Horological Machine from the brand, this is yet another timepiece that packs a massive punch. While some of MB&F’s design characteristics are immediately evident (the convex time-indicator, flying balance wheel), this is the first timepiece to be a crossover for design elements in both the Horological Machine and Legacy Machine lines. That flying balance, first appearing in the LM1 a decade ago, has finally made its way to a Horological Machine. From a collector perspective, it’s a crossover that perfectly fits the brand’s core ethos – it’s playful, it’s innovative, and it’s deadly serious fine watchmaking.

It’s on the watchmaking side of things that we find the “Bulldog” in the HM10’s design. While the Bulldog’s eyes are the time-indicating convex domes, the “ears” take the shape of two crowns on the tail of the timepiece – one for winding, one for setting the time. While flipping the HM10 over, the coolest and most directly “dog-related” design is the power reserve indicator. In the form of a bulldog’s jaws, an open, smiling jaw means the watch is fully wound while a clenched jaw indicates it’s time for a wind. With a 45-hour power reserve and a surprisingly comfortable fit on the wrist, thanks to the timepiece’s light titanium case, the HM10 Bulldog is yet another utterly mad creation from the creative geniuses at MB&F.
