Fitted with a 42.5 mm round case in 18-carat rose gold, the Academia Mathematical watch is adorned, like all DeWitt watch creations, with the brand's emblematic imperial columns. Entirely designed and hand-assembled within the Manufacture by our own master watchmakers, the Academia Mathematical watch, DeWitt's 4th Concept Watch, is the fruit of months of research and development.

Comprising 384 pieces, the Mathematical movement is based on the DeWitt Manufacture automatic caliber, most of the components of which have been produced in-house, and all of which have been hand-assembled by our master watchmakers. It operates at a frequency of 21,600 vibrations per hour and features a screwed balance and a 48-hour power reserve. With its bridges decorated with both circular and beveled ‘Côtes de Genève’ patterns and its circular-grained mainplate, all the movement's finishes are hand-crafted.

DeWitt's mystery watch concept bears witness to the passionate interest in mathematics shown by its founder, Jérôme de Witt. Far removed from the conventions of traditional watchmaking, the numerals indicating the hours and minutes give the impression that they have been scattered, thrown into chaos so that in the end they can give the precise time. There are no hands, but rather totally autonomous jumping numerals that come to life by lighting up in the center of the watch to indicate the passage of time.
