“For our customers in the watch industry, manufacturers or suppliers, it is not only important how an object looks, whether the glasses have scratches, and the metal surfaces are really perfectly smooth. The technical aspect is also extremely important: every component has to fit 100 percent perfectly. For instance the mechanism of a watch with more than 1,500 components can only function if each one is perfectly polished,” knows Regional Sales Director Xavier Fourny, who works with customers from the luxury goods segment at Pureon. There is no question about it: anyone who sells mechanical watches for 10,000 francs or more leaves nothing to chance. Balance wheel, escapement, gear train, dial and hands, case and bezel, polished pushers, levers, and screws – a watch is a total work of art. The creator must be very accomplished.
Above all, he needs skills in precision mechanics and materials processing to successfully orchestrate a precise interaction of all components. Each component only fits when the surface structure is right. Only in this way can a movement function in a technically optimal way and fully develop its aesthetics. This is not only true for mechanical timepieces.
Pureon makes its contribution to the total work of art in materials processing. Mostly it is about sapphire and rubies, mini-rubies used for bearings of gear wheels. Or lapping and polishing the tiny components down to the heads of a screw made of steel, metal or even ceramics. The customer can submit mechanical engineering drawings and detailed specifications for this, which require diamond grits in the small single-digit μ range for mirror polishing. Absolute precision work in miniature.
However, Pureon’s big plus is not the size of the grit per se, but the uniform grit size distribution that can be reproduced at any time. There is not a single grain in the diamond powder that is too coarse, which could lead to scratches and undesirable roughness during polishing. The highlight?
