MB&F HM4 Thunderbolt continuous the HM range in grandeur

Well MB&F (Maximilian Büsser & Friends) seem to have a thing for dual dials. After the HM1 Watch, HM2 watch, and the HM3 “frog” watch it’s time to take the Horological Machine (HM) series further. And for the HM4 Thunderbolt, which took three years in making, the company has put to use a complex HM4 engine and the infamous dual dial for time and power indications. The casing on top and at the base is made of transparent Sapphire glass.

The chronograph has 50 jewels and 311 components inside. The bezel spots five sapphires and the watch is finished with black hand- sewed calfskin strap that comes with a titanium and white clasp. The watch is priced at $158,000.
