Disc needle: the surface of a watch
The dial and hands of a watch are mainly used to tell the time.

Of course, there are also a few brands that do everything by themselves (including homemade dials), such as Rolex and Parma Johnny.
There are many difficulties in making dials? Sometimes, a tiny scratch or dust in the final cleaning process will make the dial useless. Another problem is that the dial is very fragile. Sometimes the yield of a dial with complex design is quite low, and it may take four or five original discs to get a genuine one. This can also explain why some dials can greatly increase the price of watches and clocks.
