MB&F HM5 RT: On the Road Again [Video]
Max Büsser doesn’t do normal. His MB&F Horological Machines continuously push the limits of what we consider a wristwatch with each new model. The MB&F HM5 RT continues to the limit-pushing, but this time in the direction of automotive design… the Lamborghini Miura, to be precise.
When you look at the MB&F HM5 RT, it’s easy to see the inspiration of the Miura in the louvers on the back of the watch which hearken back to the Miura’s rear window and in the prism-magnified time projection on the dial that looks decidedly like a dash instrument cluster.
Speaking of “prism-magnified,” with the HM5, MB&F introduced a new way to display time. Two rotating discs, mounted horizontally on the movement, indicate the time (kinda’ like a jump-hour and jump-minute). Only, instead of simply having a window displaying the hour and minutes, the HM5 has a sapphire prism that projects the time on a 90-degree angle and magnifies the display by 20 percent. It works sort of like a periscope.
The movement… sorry, engine at the heart of the MB&F HM5 RT is a 30 jewel automatic with MB&F’s trademark 22k gold “battle axe” winding rotor, a 42 hour power reserve and 224 components. Housing the engine is a water-resistant titanium housing, which itself sits inside a brushed rose gold and titanium case. At 51.5 mm x 49 mm x 22.5 mm, the HM5 RT could never be considered small. But, it is a very, very good looking watch.
The MB&F HM5 RT is limited to just 66 pieces and will set you back $82,000. For more info, check out the tech specs straight from MB&F and video below, or visit MBandF.com.
