The development of clocks and watches has a history of hundreds of years. It was first introduced to China from Western countries. Because of its simple, accurate and convenient timing function, it is used by more and more people. With the development of scientific and technological civilization, timekeeping tools emerge in an endless stream, such as mobile phones, computers, etc. Most of today's watches are used as decorations. The material of the watch has also been developed from the original single plastic or metal to various alloy materials, such as: titanium-containing stainless steel, semi-steel, stainless steel 904L tungsten steel, ceramics, plastics, titanium alloys, etc.

The development of watches has gradually become a refined and high-end development, and watch manufacturers are increasingly pursuing the quality of details. Pursue the improvement of details and styles. A high-end watch, if you zoom in, you will find that there will be a circle of numbers and various symbols, brand LOGO, etc. on the metal surface of the reverse side, which represent the type, model, material, etc. of the watch movement. Some even marked the limited edition number. These are helpful for the traceability of watches and standardize the market order.

So, how are these marks engraved? I'm going to talk about it in detail today. The back of the watch is basically two types of metal and plastic, and in order to highlight the sense of luxury, most of the watches are made of metal. For the back of the watch, which is often in contact with the skin and rubbed against the skin, watch manufacturers choose to use laser marking technology for marking and engraving.

Laser marking machine is a device that uses high-energy laser beam to irradiate the surface of objects to achieve the effect of marking and engraving. QR codes, logos, etc., can be easily completed.
