Watch carved hollow craft and craft are all rare in the field of advanced watchmaking world heritage, but because of technological limitations, the need for skilled watch master to master, but now they are facing lost The dilemma ...... Patek Philippe Ref.5180 Hollow craft engraving space art In Europe, the art of carving has long been used as a decoration for handicrafts by the goldsmiths of ancient Greece and ancient Rome, and they can carve out several patterns with only one small engraving knife. European carving art in the 15th and 16th centuries has been widely used in jewelery, watches, and even armor and weapons. Au Petit Millenary Chalcedony Tourbillon openwork watch Derived from the carving art watchmaking: hollow craft, it and paper-cut art has the same purpose. Once a crisis of lost circulation, the craft was finally revived in 1930. Watchmaking master to ordinary movement as the foundation, the first need to use the hollow part of the hole into a small hole, remove excess metal, and then use a carving knife to trim all edges into a 45 ° angle bevel and the movement of carved into different patterns . In this extremely beautiful process, they must also minimize the obstacles that see the underlying movement. If you use a metaphor you are most likely to be familiar with to tell you what is called a hollow table, it is paper cutting. The two arts are common: the molding, the extra part of the pattern should be removed, the skill should be skillful, and the finished product should have no extra burden, which is the top process that can not be wrong at one step. [page] Guilloche pattern regular logic Guilloche is vividly translated as "guillotine", which evolved from the French Guillochis meaning an exact, regular, engraving process with straight and circular patterns created by the machine. Just like the European-style gardening process, the combination of lines and geometric lines make it a charming design. Guilloche relies on a machine with engraved and engraved ring engraving called "Rose Engines" that uses the power of the fingers to control the depth and uniformity of the engraved surface. Traditional lathes are fixed-work moving heads, while Guilloche is fixed-head moving works. This requires a high degree of experience and skill, because the shape and depth of the carved patterns are almost always done by the craftsman's hand. This technique has also been very common for the past century, but the number of artisans now is falling sharply, almost disappeared and maintained by only a handful of artisans. [page] Movement chamfer beauty The establishment of the Geneva mark was originally a product of local protectionism. More than 100 years ago, movements in other parts of Switzerland went on sale in Geneva, creating intense competition that threatened the survival of local watch factories. To protect local industry, the Geneva government passed the Geneva Seal Act, allowing local watch companies to use half of the emblem, which is the shield emblem of which the eagle is half the key. Of course, in addition to having to be a local manufacturer, the manufacturer must also meet the requirements of 12 codes in the handling of the movement. The Geneva Seal Rule sets out in detail the norm for high standard production in every part of the movement, almost entirely the standard for polish. Such as "chamfering" requirement is to move all the acute parts of the movement (including right angle) all polished obtuse angle. The watchmaker grinds the sharp parts of the part with a grinding wheel and then polishes it, all by hand. After chamfering movement can not see any sharp edges and corners, which also improves the reflection of light. Will not leave any dark corner of the movement, for the appreciation has brought great convenience. [page] Gold jewelry process polished luxury Nowadays, under the impact of precious metals, the status of steel watch seems to be somewhat shaken. In fact, the use of precious metal processing technology in the all-steel watch, the added value of its hand will be far greater than the value of precious metals. This use of gold on the steel craft mainly by the "polished" and "drawing". Basically a good steel watch as the movement of the "horn," all its parts have to go through manual grinding and polishing. After this treatment of steel, will show a very different feel and luster. The drawing process will be based on the different processes, there is a slight change of lines, thus changing the overall gloss of the table.
