Know-How

Among some 500 existing watch-making brands, only very few produce their own calibres, and no more than 4 are able to manufacture their dials in-house. DeWitt is a fully-fledged watch Manufacture that is both independent and self-sufficient in terms of production, where high-end watch movements and dials are produced and developed by hand. Jérôme de Witt, with his team of extremely well trained and specialized watchmakers, is the source of many patents and technical innovations.

Every DeWitt watch is produced in-house by hand in limited edition or small series, with the emphasis placed on quality, exclusivity and skilled craftsmanship.

Workshop

With over 5000 square metres of surface spread over three floors and 60 employees, the DeWitt Manufacture, located in Geneva, Switzerland, houses all traditional watchmaking activities, from design right through to production and quality control. The brand also fully integrates the extremely complex know-how required for manufacturing its dials in-house.

A word from Jérôme De Witt
Each timepiece is created in a constant search for beauty, outstanding quality, and the most advanced horological innovations.

Dial Manufacturing

MANUFACTURING : all the movement and dial components are produced in-house in our prototyping workshop.
POLISHING: each piece is polished by our polisher on a hand lathe, for a rounded effect, or manually with a chisel for a flatter finish.
Guilloché : guilloché-work is an ancient technique consisting of engraving a fine, repetitive pattern in a given material. DeWitt strives to perpetuate ancient watchmaking traditions by continuing to pursue the art of guilloché-work on its historic 18th and 19th century machines.
ELECTROPLATING: electroplating consists of colouring each dial component. A thin layer of metal (gold, ruthenium, silver, palladium, etc.) is electrolytically deposited on metal parts in order to obtain different shades.
ELECTROPLATING: each dial component is placed in a kind of basket and immersed in a bath for electrolytic treatment.
ELECTROPLATING: Some baths correspond to standard colours used in watchmaking (pink gold, silver, rhodium, etc.) and others are chemically developed by the electroplater.
ASSEMBLY: all dial components are hand assembled. Some DeWitt dials are composed of 45 different elements. All these elements are set by our assemblers. Mother-of-pearl is also cut out at DeWitt.
TRANSFER: some designs are painted on the movement (logo, numerals, patterns, etc.). A manual machine fitted with a gelatine stamp applies the paint on the dial. The piece must be dried in the furnace between each application.
CONTROLLING: All the assembled dials are controlled following the very demanding norms established by the DeWitt Manufacture.
With their light and texture effects, daring combinations of materials and colours, as well as sophisticated constructions, DeWitt dials are characterised by their original design, always pushing back the technical and aesthetic boundaries.

Finishing, assembling and control

DeWitt can count on a team of extremely well trained and specialized watchmakers whose knowledge and skill are by far the company’s most valuable asset.
All finishings are done by hand following very demanding finishing norms established by the DeWitt Manufacture (Circular Côtes de Genève, satin-brushed surfaces, circular graining, bevelling,…)
Each DeWitt high-end watch movement is assembled by hand and controlled by one watchmaker.
As ultimate crowning and seal of quality high complication watches receive engraved the signature of the watchmaker.
Every DeWitt watch is produced in limited edition or a small series, with the emphasis placed on quality, exclusivity and skilled craftsmanship.
Jérôme de Witt, the founder of the Manufacture, is the source of many of their patents and technical innovations, including the Oscillating Peripheral Rotor, the Force Constant with chain, the Automatic Sequential Winding (A.S.W.), crown reclining system,…
DeWitt also expresses its creativity through concept watches, true works of art dedicated to admirers of technical performance.

The Museum

Displaying one of the world’s largest collections of tools with over 250 objects dating from the 18th and 19th centuries, the DeWitt museum, also located at the company headquarters, retraces almost three centuries of hand-crafted watchmaking.
