The HM4 Thunderbolt is a wristwatch inspired not by a car, but by a plane. Yes, we know we always cover cars, but planes are still in the high speed category and this is a very cool gadget. Give us a break. It’s cool, expensive, and we are going to tell you about it.
The HM4 Thunderbolt Watch features an aviation-inspired case and engine. It includes 50 jewels and 311 components in its engine, five sapphire crystals, and a black hand-stitched calfskin strap with a titanium and white cold clasp. The only simple thing about this watch is how it tells time; it has the traditional dual dials – one for the time, one a power indicator - but the rest is just exquisite.
The inspiration behind the timepiece comes from Maximilian BГјsser's childhood passion for assembling model plane kits. This passion was the right type of fuel to ignite the aerodynamic characteristics of the Thunderbolt's titanium and sapphire envelope with an added futuristic touch. The striking transparent sapphire section of the case requires over 100 hours of machining and polishing to transform an opaque solid block of crystal into a complex, exquisitely curved panel allowing the light to come in and the beauty of Thunderbolt's engine to stand out.
There will only be 20 units produced, each carrying a price tag of $158,000.
