Lead: They are thinner than your hair, but it is the soul of the movement. To balance the swing, but also balance the left and right sides of the very law, the most important thing is the gossamer. It's about the stability of your movement, just like the heart. Mechanical watches hairspring mechanical watches hairspring You can see the balance wheel can swing around, entirely because of the gossamer, some say that gossamer is "Balance-Spring", also called "Hairspring", as its name implies is like a hair as thin springs to swing the balance of the law The soul exists. Hairspring in the watch, is a long way to go, it is the soul of a mechanical watch, but also a movement of all parts of the lightest part. In short, if a watch is not allowed, it is a gossamer flaw, gossamer material, gossamer thickness, gossamer length, flexibility can determine a table is accurate. Balance wheel for the non-stop spring on the chain, and balance springs so that the balance to start work, a watch's basic role and essence is to rely on these two complement each other, each other. A balance wheel swing frequency, fast and slow is determined by the gossamer length and balance wheel scale, the control mechanical watch power transmission is stable, but also generated. Gossamer every contraction, it seems to draw a perfect circle, a call to a stable suction before they can balance wheel. In recent years, many brands main tour hair silk with silicon, etc., in fact, the perfect hairspring, the material accounted for a large part of the decision. Hairspring, in order to resist temperature differences, resistance to gravity, resistance to wear and tear, the impact of the magnetic field is difficult to resist these invisible factors, will keep the gossamer metal aging, non-magnetic, and then your watch decisive Negative effect - not allowed to go. Early 20th century Nobel laureate Charles Edouard Guillaume invented the use of a new alloy Invar to make hairspring, its advantage is not affected by temperature, anti-magnetic. In addition to material, shape is also a major determinant of gossamer. Until Mr. Breguet invented a kind of "Overcoil" hairspring, this contraction and expansion could be improved. Overcoil is to create an arc, the end of the spring wire will be like an arc, covering the original hairspring. This must be done by senior watchmaker hands-on twist, and must be manually adjusted. In the watch industry, adjust the teacher is the most professional watchmaking profession. The operation of the teacher is composed of five components of the clock core: balance wheel, balance wheel spindle, hairspring, hairspring inner pile, hairspring outer pile. The hairspring operator continuously detects whether the hairspring and balance wheel are in good parallelism and then places the assembled hairspring and balance wheel on a special "leveling device" to perform the most delicate operation at the operator Ascending curve, the device allows the two components always parallel. This procedure is designed to ensure that the hairspring stretches in concentric circles rather than being eccentric so as to avoid any imbalances that cause the clock to run faster or slower.
