Classification of watch movement?

Generally speaking watch movements can be divided into two categories: mechanical watches and electronic watches. And mechanical watches commonly have two subcategories, manual mechanical watches and automatic mechanical watches. Electronic watch movement commonly has 4 types: 1. digital quartz electronic watch 2. pointer quartz watch 3. automatic quartz watch 4. actinic watch. Below is an introduction to the classification of these watch movements!

Mechanical watches: 1. manual mechanical watches 2. automatic mechanical watches

Mechanical watches second hand is continuous and uninterrupted. Because of the complexity of the mechanical watch movement, the timing error is larger (depending on the brand), the chronometer movement error is smaller, the error of a day within -4/+6 seconds is normal. Mechanical watch timing error can not be cumulative, the watch over a period of time need to debug fine craftsmanship, easy to use, full winding can go more than 36 hours. The movement can be used for a long time. Appearance to be thicker than the quartz watch (depending on the brand), there are some brands are also very thin, but generally are manual mechanical watches.

Electronic watches: 1. digital quartz electronic watches 2. pointer quartz watches 3. automatic quartz watches 4. actinic watches

Quartz watches are very accurate in terms of timekeeping, generally requiring a monthly difference of 15 seconds or less, and there are two types of three-hand and two-hand. The movement uses integrated circuits, the structure is much simpler than the mechanical watch movement, and the assembly is very simple. It is easy to use, no need to wind up the watch, and a battery is generally available for 2-3 years. However, some quartz watches use lithium batteries, which have a long service life and can be used for about 7-8 years. Quartz watch prices are relatively cheaper than mechanical watches (the same brand with the same style), but some high-grade brand quartz watches are expensive because of the brand is good, the appearance of good materials (18k gold or diamonds or precious metals), the appearance of the design is excellent, resulting in some quartz watches than the general value of the mechanical watch is high.
