What is the structure of the automatic mechanical watch？Look at today's article:
Automatic mechanical watch anatomy is quite hard to understand for those new to it. In this article, I will lay down the basic information of the automatic watch anatomy. The watch diagram below will show you the parts of a watch as well as its name.
Aperture: An opening on the watch’s dial. It can be used to show the internal automatic movement
Bezel: The edge of the case with the dial window. Some of the more popular usage/types of bezel are:
1) Unidirectional bezel with minute markers (diving bezel): This bezel is usually for diving watches. The minute markers is used to keep track of time underwater. Simply set the “00 Minute” to the minute hand when starting the dive. As you dive, the minute hand will move and you can see how many minutes has elapsed during diving.
The unidirectional is keeping the bezel to be rotated only anticlockwise. It can’t be rotated clockwise as this will cause problems for divers to keep their diving time in check. You can see the Seiko SKX007 above for an example of a diving bezel.
2) Normal empty bezel: Dress watches usually have an empty bezel. It helps them to achive the clean and sleek look a dress watch need.
3) Tachymeter scale: The bezel is used to place the tachymeter scale on top of it. The scale can be used to calculate the speed of a moving object and is typical for any racing or sports watch
4) Telemeter scale: Telemeter scale is put on top of the bezel to make it easy for its user to calculate the distance from him to an event that happened far away, provided he can see and hear the event. Example of events are artillery firing, lightning and bombs. The scale is set based on the principle of speed of sound and typically seen on a military watch. (The Victorinox Infantry Vintage above has the telemeter scale, but it is positioned on the dial and not on the bezel.
5) World Time: Bi-directional rotating bezel that can be used to determine the time at other time zones.
