Sherman doesn't walk, talk, weld cars, or roam Mars. He doesn't try to kill Sarah Connor, help Luke Skywalker, warn Will Robinson, 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.

The movement plates and bridges of the clock make up the skeleton and body of the robot; Sherman’s mainspring barrel bridge extends down to support his rubber caterpillar tracks, movement spacers act as shoulders for the arms, and his eyes are bolt heads supporting the regulator. The transparent dome on Sherman's head reveals his mechanical brain. Sherman's arms can be manipulated into nearly any configuration, and his hands can be used to hold items.

8 days power reserve

8 days power reserve

Sherman's mechanics are based on a L'Epée in-line eight-day movement, which ensures that the friendly tank-treaded table clock can display the correct time for more than a week before rewinding.

Clock regulator

The clock regulator’s gentle beating and intricate composition are made visible thanks to its polished glass dome cover. If the protective dome acts like a skull, then the regulator symbolises Sherman’s brain at work.

His rubber caterpillar tracks are fully functional and, with a little help from a friend, he can roll over the rugged terrain of a typical office desk.

L’EPEE 1839

Epée 1839

For over 175 years, L'Epée has been at the forefront of watch and clock making. Today, it is the only specialised manufacture in Switzerland dedicated to making high-end clocks. L'Epée was founded in 1839, initially to make music box and watch components, by Auguste L’Epée who set up the business near Besançon, France.

L'Epée is now based in Delémont in the Swiss Jura Mountains. Under the guidance of CEO Arnaud Nicolas, L’Epée 1839 has developed an exceptional table clock collection, encompassing a range of sophisticated classic carriage clocks, contemporary design clocks (Le Duel) and avant-garde, minimalist clocks (La Tour). Complications including retrograde seconds, power reserve indicators, perpetual calendars, tourbillons and striking mechanisms – all designed and manufactured in-house. Ultra-long power reserves have become a signature of the brand.

Conceived and developed by MB&F, engineered and crafted by L’Epée 1839, 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 name – as his continuous tracked undercarriage hints at – is derived from the prolific M4 Sherman tank used by the USA and its allies in World War II. Officially called the Medium Tank M4; it was dubbed the Sherman M4 by the British, who named it after General William Tecumseh Sherman. While the name may have originated in a war scenario, he is most definitely a robot of peace, since Sherman is fitted with the most powerful weapon of all: the ability to make you smile.
