Watch manual classification of craftsmanship

At present, guilloché is the best embodiment of handcraft on the watch. This is a nearly lost process, more than a decade ago in Germany, France and Switzerland were restored. Gui Lou, also known as Rose Engraving Machine, this process with mechanical rotation, in the pre-designed pattern plate carving a variety of decorative patterns. This process relies on manual control of the uniform engraving, so although the machinery, but more biased in the manual process. At present, less than one hundred masters can master the skills of using Ji Lou craft. Recently, many factories quickly produce guilloche through industrial means such as stamping, friction pressure or carving machines. But the real high-grade watch with only hand-Gu Lou. Breguet and a few high-end brands are still using Gui Lou technology. Interestingly, to distinguish between the fast and cheap pseudo-guillemots on the market, Breguet printed guilloché letters on his guilloché dial. And the addition of this main word is somewhat ironic for the current massively hand-made watchmaking industry. The vast majority of Breguet dials, except Fritillaria material and sports dials, are used manual Gui Lou. This craft makes Breguet watch attached to a lot of manual value. In the history of watches, the British watchmaking (from astronomical clock to pocket watch), whether the clock's precision or beauty, reached the most brilliant period in the past century. British watchmaking in the modification of the movement reflected height, has not been exceeded. Because British watchmaking is very harsh on craftsmanship, Swiss watchmaking places more emphasis on industrialization and modernization. Swiss brand in the modification of the movement inherited the traditional craft of ancient clocks not many brands, Breguet is one of them. Because Breguet belonged to a French watch brand with a similar status to the British watch. Mirror polishing spéculaire / black polishing, more common in pocket watches and some independent tabulation works, such as Philippe Dufour, Roger W. Smith and so on. English means black polishing, as the name implies, is due to its smooth and mirror-like surface without scratches or rough, often reflecting the darker light inside the room, looks like a black surface. Mirror polishing is extremely challenging, as a slight scratching on the part is a bit careless. Polishing process requires superb technology and patience. The polished parts show the color of the part (gold, red gold, steel) and contrast with other finishing processes (such as matte finish), giving the movement a color depth and contrast. Frosting (frosting), in the movement of the K gold parts produce a similar golden matte effect more common in pocket watches and some high-level watches, such as Breguet 7027 and the British independent watchmaker works. In fact, the bulk solution of most Swiss brands is sand blasting. After careful observation, the sandblasted surface is the texture of the egg shell. The real matte finish is polished by a grinding wheel with a very thin steel brush, which requires the technician's hand to be extremely stable. Parts have many small edges or grooves must be polished to and must be uniform. This process takes time and labor, the Swiss brand has not seen use.
