watch, it's a horological machine. The HM4 Thunderbolt, recently unveiled by designer Maximilian Busser, represents an intriguing mixture of high-grade materials, precision engineering, and outlandishly macho design. The case is composed of titanium and sapphire -- which collectively take over 200 hours of machining and finishing to achieve the desired aerodynamic look -- while ensconced within it are over 300 parts composing a "transcendental" engine. We can't say we're not attracted by the bullet-shaped dials offering us our time with a side order of superfly, but then the $158,000 price tag ensures that we won't be able to do something foolish like buying one for ourselves. See the HM4 on video after the break.
