The MB&F HM4 Thunderbolt Watch is purely inspired from the Thunderbolt A10 fighter jet. This luxurious timepiece has dual dials: One indicates the time, while the other works as a power indicator.

The case of the HM4 Thunderbolt Watch is made of titanium, with five sapphire crystals on it. There are an additional 50 jewels and 311 components in the watch, and it also has 72 hours of reserve power. With a price tag of $158,000, MB&F will produce just 20 pieces of HM4 Thunderbolt Watches for 2010.
