Introduction of button batteries commonly used in quartz watch movements
Although there are more than 20 types of button batteries commonly used in quartz watches, the batteries used in quartz watches of various specifications are regular. The functions of the quartz movement are divided into the following categories. Regardless of the manufacturer's quartz movement, the batteries are basically used according to the following table. As long as the following types of batteries are available, more than 80% of the quartz watches can be covered. In addition, due to the different naming of battery models in different countries, please refer to the table below for comparison. In the article, I will list three main naming methods (Japan/Europe/Europe/China) at the same time. They all refer to one model.
Standard quartz movement: SR626SW/377/AG4 battery
The standard quartz movement includes no calendar, single calendar, or dual calendar. The thickness of the movement is generally 3mm or 3.15mm without the calendar, 3.7mm-4.15mm with calendar, and battery life between 24 months and 40 months. The standard quartz movement is the one with the largest capacity in the quartz movement, and it basically uses the SR626SW/377/AG4 battery
The following are the most commonly used standard quartz movements:

(CITIZEN) Miyota 2035
Seiko TMI PC21
Epson AL35E
ETA803.112
Slim quartz movement:SR621SW/364/AG1 battery
The thickness of the slim quartz movement is generally 2.2-2.3mm without a calendar, the thickness with a calendar is about 2.7mm, and the battery life is about 3 years. The thin quartz movement requires a thin battery, and it is basically used an SR621SW/ 364/AG1 battery
The following are the most used typical movements of slim quartz movements:

Super slim quartz movement: SR616SW/321 battery
The thickness of the Super slim quartz movement is generally 1.9-2mm without a calendar and 2.3mm with a calendar. The battery life is about 3 years. The ultra-thin quartz movement basically uses SR616SW/321 batteries.
The following are the most used typical movements of the Super slim quartz movement:

(CITIZEN) Miyota 9T33
Mini quartz movement: SR521SW/379/AG0 battery
The Mini-type movement is extremely small in size. It is only 5.8 mm long and wide when used on women’s watches. Therefore, the battery needs to be very small. The battery is SR521SW/379/AG0. The battery capacity is only 7.5mah, which can last for 2-3 years.

Multifunctional quartz movement:
Multi-function movement is also called multi-eye movement. Generally, there are more than two auxiliary function sub-dials, such as a week, calendar, monthly calendar, 24 hours, moon phase, etc. The batteries used in each multi-function movement are different. There are mainly the following four types, and the battery life is about 3 years:
SR626SW/377/AG4 battery
SR621SW/364/AG1 battery
SR920SW/371/AG6 battery
SR927SW/395/AG7 battery
(CITIZEN)Miyota 6p27
(sekio)TMI VD75
S.Epson VX3j
Chronograph quartz movement
The multifunctional chronograph movement is equipped with a chronograph function. The granularity is from 1/5 second to 1/20. Generally, a larger capacity battery is required. The battery life is 2-3 years. If the chronograph function is not used, the battery can last longer. some.
