Introduction
A piece of avant-garde horology that defies conventional design principles, the MB&F HM4 Thunderbolt was launched in 2010 taking inspiration from the aerodynamic principles of aeronautics, resembling the shape of an aircraft's fuselage and wings. The case, crafted from high-grade titanium, is both lightweight and exceptionally durable, offering a futuristic look that's both sophisticated and edgy, as per the design language that has defined MB&F since their founding. Powered by a custom-developed movement that perfectly fits it unique case, it features a manual wind with a 72-hour power reserve, displaying hours and minutes on one side and a power reserve on the other, through highly legible, vertically oriented dials. The use of sapphire crystal sections reveals the intricate mechanics within, showcasing the beauty of the movement's complexity, and the artisanal craftsmanship that MB&F has poured into this timepiece. Limited in production, the HM4 Thunderbolt epitomizes MB&F's philosophy of pushing the aesthetic and mechanical boundaries of traditional watchmaking.

THE DIALS
With its vertically orientated dials, the HM4 is easier to read than one might assume, with its display reading just like the dials inside of an aircraft.
THE CONSTRUCTION
Designed to look like the thrusters inside of an aircraft's engine, the hM4 Thunderbolt embodies MB&F's whacky design language in its complete totality.
TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
Watch is in excellent overall condition. The watch has superficial wear visible, with some marks along the brushed titanium case, as well as bezel of the dial apertures. Consistent minor wear visible on the deployant clasp. Please note that the watch comes with original box and papers, but the guarantee paper is blank and not filled out.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
Our Perspective
Aesthetically unique and horologically impressive, the HM4 embodies everything that has enabled MB&F to become as successful as they are today, with its incredibly unique design and impressive engineering.
