Catalogue Essay
For the free thinker, the irreverent, and the bold, MB&F’s Horological Machine 4 embraces the unexpected. Introduced in 2010, it has drawn collectors and enthusiasts for over a decade with its powerful and inspired design as well as its technical prowess.
The design of the Horological Machine 4 is directly inspired by the fuselage of the P47-Thunderbolt fighter plane. The movement took three full years to develop and is ingeniously placed on a horizontal plane. Dual mainspring barrels drive two vertical gear trains, transferring power to the dial indicating hours and minutes on the right and power reserve on the left.
Made in only 50 pieces in titanium, the case is quite light for enhanced wearing comfort, and regardless of its unusual ergonomics, the watch sits very well on the wrist and could even be considered the perfect pilots’ watch.
The present HM4 comes directly from the collection of the original owner, an important collector of independent watches, and its movement is personalized with his name. In well-preserved condition, the watch comes complete with all its original accessories.
Please note that MB&F generously offers a complimentary servicing of the watch and removal of the personalization to the winning bidder within a period of 6 months after the sale.
