The movement of the Black colour wrist watch has a sophisticated and complex structure, but its size is small. A large watch has a movement of no more than 30 mm in diameter, which is only a little larger than a dollar coin; a small watch has a movement of less than 20 mm in diameter, which is only the size of a dime coin. The weight of a men's uniform movement watch is the most complete, but it is about 40 grams, which is less than one or two weights; while the movement weight is only 15 grams, which is only three points, and the women's watch is even lighter.

Black colour wrist watch products

Such a small movement needs to be assembled with more than one hundred parts precision manufactured from dozens of high-quality raw materials, so the various parts of the Black colour wrist watch movement are very precise and compact. Black colour wrist watch movement is a machine that runs around the clock for one minute and one second. If calculated by the high-frequency hand-loading with a frequency of 21,600 times per hour, the balance wheel in the movement keeps swinging back and forth 518,000 times every day. Thousands of times, more than 189 million times a year.

Black colour wrist watch production is characterized by small part size, high processing accuracy, high finish requirements, fine process equipment, high degree of mechanization and automation. Knowing how the Black colour wrist watch is made will help us better grasp its performance characteristics and use and keep it correctly. Below, briefly introduce how the Black colour wrist watch is made.

There are many raw materials for the manufacture of Black colour wrist watch, and there are strict requirements on the performance, surface condition and dimensional accuracy of the material. For example, the material for the hairspring requires high strength, anti-magnetic properties, and is less affected by temperature changes. It is made of a special stainless, constant elastic alloy material; the clockwork of a watch is the motive power component that drives the entire movement to keep running. This requires the use of stainless, non-breakable, high-strength, and high-elastic materials; the "diamond" in the watch is a kind of artificial gemstone with extremely high hardness and excellent smoothness to improve the flexible operation and durability of the parts. Abrasiveness, prolong the service life of the sub-watch.

The quality requirements for the processing of various parts in the Black colour wrist watch are very strict. For example-a balance wheel journal as thick as a hair, its tolerance is only 0.005 mm, and it is riveted with the balance wheel after it is checked by a 40-fold microscope. The structure and shape of the splint have the most changes, especially the main splint is more complicated, with a large number of holes and grooves, not only on the plane, but also on the side, there are also horizontal holes, the size and shape of the holes are very diverse; There are also many irregular geometric groove shapes in the groove, and their positions are distributed on both sides of the main splint, and some have to penetrate each other; in addition, there are many piles and convex altars on the main splint, so in watch parts, it It is a part with the longest manufacturing process, the most man-hours, and the most process equipment.

Assembling the various parts that have been processed and inspected is the final stage of making a watch. The assembly of the watch requires very strict requirements and is carried out in a clean, constant temperature workshop with air-conditioning equipment. When you walk into the assembly line of the watch assembly workshop, you will see rows of assembly workers wearing white coats, white hats, slippers, and rubber finger cots on their fingers, just like the doctors in the operating room. , The movement of the watch is carefully assembled and adjusted. The smallest screw in a watch is much smaller than sesame seeds. A balance wheel journal is only as thin as a hair, so that it can only be adjusted carefully by a microscope with a magnification of several tens of times during assembly. For the escapement parts, use a projector to magnify fifty times and inspect them one by one. After the assembly of a Black colour wrist watch is completed, it will be fully checked for more than ten days. It will undergo simulation, actual running, second check, vibration measurement, electronic meter test, appearance and other assessments. After passing the test, Before leaving the factory.
