Greubel Forsey Introduces the Entirely Hand-Made Tourbillon Watch
The Hand Made 1 is a watch “95%” produced “using only hand-operated tools”, requiring some 6,000 hours, according to Greubel Forsey. That’s equivalent to three years of work, largely performed by a special team of watchmakers assembled by Greubel Forsey specifically for this project, along with independent specialists who produce certain components. Functionally, the Hand Made 1 is a straightforward timepiece – it shows the time, hours, minutes and seconds, and is equipped with a one-tourbillon regulator. The movement is made up of 272 parts, which is within the usual range for such a movement. The complexity of the watch comes from how it is made – by hand or by hand-operated tools – which is why only two to three examples will be produced per year. The genesis for the Hand Made 1 is the department within Greubel Forsey that produces prototypes, which are essentially one-off, hand-made watches. The same production techniques are applied to the Hand Made 1, except that they are taken to a far higher level, in order to create components that are produced with the same techniques as prototypes but to the same fit and finish as standard Greubel Forsey movements. So each screw is made on a manual lathe, and can take up to eight hours to complete. The case components are milled on a pantograph lathe, essentially a manually operated CNC machine that requires the operator to guide the cutting tool to by hand. And even the balance spring is rolled by a manua...
