MB&F HM10 Bulldog

About this reference

The MB&F Horological Machine N°10 Bulldog Titanium was introduced in 2020 and remains part of the brand’s contemporary catalog. Collectors value this reference for its manual-wind, in-house movement featuring a 2.5Hz flying balance wheel positioned beneath a central sapphire dome. The grade 5 titanium case measures 54mm by 45mm and utilizes a unique "jaw" mechanism that functions as a power reserve indicator; the teeth close as the 45-hour mainspring winds down. Time is displayed via two rotating aluminum domes for hours and minutes. This model represents a technical evolution of the brand’s animal-themed "Machine" lineage. On the secondary market, the HM10 Titanium typically trades in the $85,000 to $110,000 range. While the titanium version features blue accents, a notable variant exists in 18k red gold and titanium, which often commands a higher premium at international auctions.
