GPHG Men’s Complication Watch Prize: Greubel Forsey Hand Made 1

Of course, in order to To fulfil this exceptional challenge and reach micron-scale accuracy using ancestral tools, the artisans must obtain a precision that such traditional machines themselves cannot easily offer. In this difficult process, the time spent is of secondary importance. Greubel Forsey had to build a team of the most skilled craftsmen in each field, principally from its workshops, as well as several external talents.

The same questions were asked at every stage: “How can we design this part to be able to make it using traditional tools or machines such a jig borer or lathe? And which shape can we give it so the artisans’ intelligent hands can ensure extraordinary precision and the finest craftsmanship?” 

Hand Made 1 – an hours/minutes/seconds timepiece with a tourbillon. The Hand Made 1 is not a known calibre, has been entirely created from scratch. Each of the 272 movement components and 36 case parts has been individually redesigned for the movement construction. ( More than 800 separate parts had to be made and tested to obtain the 308 component.) The same questions were asked at every stage: “How can we design this part to be able to make it using traditional tools or machines such a jig borer or lathe? And which shape can we give it so the artisans’ intelligent hands can ensure extraordinary precision and the finest craftsmanship?” 

The Hand Made 1because involved the people who would make and decorate each component from the very beginning. Some parts of the movement were redesigned in order to simplify them. Meanwhile for other mechanisms such as the tourbillon, the number of components had to be increased to allow each part to be made by hand. The timepiece’s relatively modest dimensions (43.5 mm in diameter and 13.5 mm thick) further heightened the difficulty of this task. Only tourbillon carriage alone consists of 69 components weighing a total of 0.521 g.

“ This new step towards the summit in the finest of craftsmanship is substantiated on the dial at 6 o’clock, where the inscription HAND MADE replaces the usual SWISS MADE.”

Conclusion: All movements of component is handmade (except sapphire crystal glasses, case seals, spring poles, synthetic jewelery and mainspring), from all the wheels that make up the movement, the case, leather strap, dial, and screws to hands.

Greubel Forsey‘s attention to detail naturally includes the performance of the watch. This new step towards the summit in the finest of craftsmanship is substantiated on the dial at 6 o’clock, where the inscription HAND MADE replaces the usual SWISS MADE.
