With the Academia Endless Drive, DeWitt offers a new way to display the power reserve using an “endless” worm screw. A system that is both ingenious and attractive.

The origin of the worm drive is not exactly known. Archimedes created a spiral model similar to the one we know today. Leonardo da Vinci drew one in his Codex. This system used in mechanics provides a way of increasing or reducing a force. The worm drive can also transform a rotating movement into a translation movement. This is the aspect that DeWitt has decided to foreground in the Academia Endless Drive. So, on the watch dial, rotating discs display the hours and the minutes. Between them, a strange mechanical construction attracts the eye. This is the power reserve indicator. Incorporating a worm screw, two movements drive it. As the 59 hours of autonomy provided by the automatic movement run down, the screw turns around. When the barrel is rewound, the screw slides up along the longitudinal axis. A two-colour red and green indicator provides additional visual information about the amount of power remaining. The complex calibre DeWitt 5050 is made up of 320 pieces.

The dial, with its hand-made black galvanic background, is housed in a 42.5mm-wide case combining pink gold and rubber. The case features the brand’s signature Napoleonic imperial column motif.

The Academia Endless Drive is worn with a black leather strap with a folding buckle.
