MB&F Horological Machine No4 THNDERBOLT is here !

For the last three years I could not talk about this amazing piece of machinery, and it is truly a great day that I can finally share with all !
After the 311 part Engine which was unveiled in March during Basel, here is probably the most complex case in the history of horology to protect and magnify it.

Titanium and Sapphire – 150 hours of machining and polishing just for the central Sapphire case (that is close to four weeks of machining for one piece !), over 60 hours of machining and finishing for the titanium case back, etc, etc… In our twenty years of horology, this is the greatest challenge Serge Kriknoff and I have been up to.

So what is the Thunderbolt ? A tribute to Aviation…
Why ? Because from the age of 8 to 12-13 I spent every free minute crafting model airplanes… They were everywhere in my room. Hanging from the ceilings, accumulating on the shelves, in the cupboards. I would spend hours assembling, modifying, painting anything which had two wings. HM4 is a very personal interpretation of what would happen if you crossed a piece of ultra high end horology with the world of aeronautics.

HM4 Thunderbolt is the next step in our creative quest for horological kinetic art.

If you have any questions do not hesitate. The whole MB&F team is looking forward to your feedback.

With our very best regards,


PS there are many more images on the download link, and to show how the Thunderbolt looks on a wrist, I included hereunder a photo of myself with my skinny wrists wearing the Machine !
