MB&F stands for Maximilian Büsser & Friends. Max and his talented friends again created three amazing timepieces. I took more than 50 pictures with my macro lens and I will show you a video … Simply click on “read more” and enjoy!
This is MB&F + L’Epée 1839 Sherman.
“He’s quite a cute little robot”, says MB&F, “but to be frank, Sherman doesn’t do very much. He doesn’t do very much at all. Sherman doesn’t walk, talk, weld cars, or roam Mars. He doesn’t try to kill Sarah Connor, help Luke Skywalker, warn Will Robinson, vacuum the floor, star in feature-length films, or enforce the law. In fact, Sherman really only does two things, but he does both extremely well. Sherman tells the time. And Sherman makes people smile, which is probably the world’s most useful and (emotionally) valuable complication.”
In his hands Sherman holds the new MB&F Horological Machine No6 SV (SV stands for “Sapphire Vision”).
Let us firs have a closer look at Sherman. Conceived and developed by MB&F and engineered and crafted by L’Epée 1839 – Switzerland’s only specialised high-end clock manufacture.
Sherman is the result of Maximilian Büsser’s on-going quest to revisit his childhood, during which he hankered for a robot friend. Sherman’s mechanics are based on a L’Epée 1839 in-line eight-day movement, which ensures that the friendly tank-treaded table clock can display the correct time on his chest for more than a week before requiring rewinding.
Sherman is launched in limited editions of 200 palladium (plated) pieces, 200 gilded pieces (gold-plated) and 50 diamond-set gilded pieces.

So let us now focus on the MB&F Horological Machine No6 SV…
The new timepiece adds an extra three-dimensional layer to the biomorphic beauty of the HM6 ‘Space Pirate’ by revealing the mechanical marvels of the unique Engine within. The complex curves of two transparent sapphire crystal plates sandwich a precious metal “streamliner” case band, creating two horological amphitheatres dedicated to the appreciation of exquisite, hand-finished micro engineering.
“I always thought that the most beautiful part of HM6 was its movement, and that it was a shame not to show it. But it was only recently that the technology of machining sapphire crystal allowed us to create such a complex case,” Max told me in Geneva at the SIHH.
At the front, two spherical domes rotate vertically, respectively displaying hours and minutes in large, highly legible numerals.
Aft, twin spherical turbines spin horizontally, driven by the rotor and multiplying gearing that automatically regulates the winding system to minimize stress and wear.
A central dome houses a 60-second flying tourbillon, the precision regulator of the HM6 Engine.
High-precision regulators are especially sensitive to changes in oil viscosity, and ultra violet radiation gradually breaks down lubricating oils. This is why HM6 features a retractable, semi-spherical, titanium protective shield; when closed, it blocks harmful radiation from prematurely oxidising the lubrication oils in the regulator. A crown at 9 o’clock opens and closes the cover in – and like – the blink of an eye.
The nine sapphire crystal domes – five on top and four underneath – are carefully fastened to the transparent plates thanks to a special gluing process, achieved under vacuum in a high temperature oven. This offers maximal strength and water resistance.
The two spherical turbines, each composed of no fewer than 15 curved vanes, are machined in two hemispheres from solid blocks of aluminium. These turbines are driven from the rotation of the automatic winding rotor by a gear train designed to amplify the number of rotations. As (air) friction increases exponentially (squared) as a function of velocity, if the winding rotor starts rotating too quickly – most likely due to highly active movement of the wrist – air friction on the turbines increases and helps counteract the excessive speed to minimise wear.
