The garnish of watch movement

Many details of a major impact on how the perceived watch. These details may seem quite small, petty, unworthy of mention. It would seem, why should we talk about things that do not even see it? But no: in the workshops of the inner surface of the Greubel Forsey protochek in platinum and bridges treated with "pearl" textured polishing, although very often the surface of the fully assembled movement are hidden under other parts. The composition of all the details - this style of finishing machinery. Style, even in this case, as the final machining of the parts of the movement - not just a trivial matter, as you can imagine. For several centuries of mechanical horology watchmakers were produced a few classic styles - Swiss, English style "Chinese" watch finishing details of the movement - is to use one of the classic styles. A good result is guaranteed. Of course, subject to the rules of the game. It is quite another - to find your own style. This is a few people can, because this little who dare to go. Greubel Forsey failed. There is a certain mystique, which Greubel Forsey, apparently deliberately around your brand: what looks like a machine, often done by hand, something that looks like a hand, may well be the engine.

Billet parts, of course, cut out using a computer-controlled machines. Although the machines currently provide the best possible quality of metal, but anything can happen - cutter worn down, blunted, and processed by machine parts on it are unevenly heated and cooled. There are burrs on surfaces that have to be flat, stay a step after consecutive passes cutters. "Vertical" the accuracy of a typical modern high-end CNC machine is about two microns, so double microned stairs - rather than a rarity, but the rule. In short, many small but vexing problems, to overcome which requires great efforts.

One method of eliminating these minor difficulties in Greubel Forsey is to use a standard used in the final processing of parts blasting technology as technology that is intermediate. With sandblasting with CNC billet obtained after removing traces of mills and at the same time check for the presence of steps and other problem areas. They are on a uniform matte background are easily visible. "Stepped" reject the details, but a good guide for final processing.

Surprisingly, the "sandblasting" type of flat surfaces of platinum and bridges attached to a special processing method, nothing to do with not having sandblasting. "Frosty" textured polishing (Frosted finish) is applied by hand using a wire rotating nozzles - as in metalworking usually remove rust or paint unnecessary. With manual processing the master can subtly feel the need to press somewhere, and somewhere reduce contact with the grinding attachment - the only way we obtain the desired uniformity of granulation.

Another must manually type the final machining watches Greubel Forsey - fine grinding of the longitudinal ends of the platinum and bridges. The word "manual" means in this case is hand-sanding wooden needle files with grit glued. According to the founding fathers, commonly used for this purpose does not drill perfectly parallel lines, as there is a significant wave-like texture. Only hand-sanding gives details of the kind of perfectly polished, as if on a lathe.

Platinum and bridges watch works Greubel Forsey are made of nickel silver - a tribute to the Swiss tradition of manufacturing high quality instruments. When they are yellow - they are gold-plated, when steel - coated with palladium, when black - nickel plated and then blackening, in some cases, nickel silver is left without coverage.

Plaques with engraved inscriptions, whether it's just information (company name, number of watches in the series, or "message of the founding fathers of the inventors) – the main finding design finds Greubel Forsey - made in gold.
