The Ultimate Plane-Geek Timepiece


Behold the HM4 Thunderbird, inspired by aeronautical engineering, released in 2010 and limited to 20 handmade pieces per year. The blurb sez:

The case of HM4 blends high-tech titanium for its lightweight and strength with a sapphire centre section offering a view into the engine. The limited editions HM4 Razzle Dazzle and Double Trouble take the aviation theme even further with real rivets in their fuselages and hand painted nose art inspired by the rebellious paintings on WWII aircraft, while HM4 RT offers an altogether more luxurious way to fly.

The Thunderbolt’s engine is the culmination of three long years of development. Each of the 300-plus components – including the regulator and even the screws – was developed specifically for this anarchistic calibre. Horizontally configured dual mainspring barrels drive two vertical gear trains, transferring power to the twin pods indicating hours/minutes and power reserve.

Mid-range price: a trifling $158,000.

We’d have the Razzle Dazzle.
