SHIJIN CALENDER WATCH TYPES
Affordable Perpetual/Affordable Annual Calendar Watch Varieties:
1. Monthly calendar: just a simple calendar, that has a date display, usually generated by a disk.
2. Day Date: has a date and day of the week display.
3. Full or complete calendar: adds a month display, so it includes day, date month, and sometimes moon phase.
The there above types of calendar watches must be corrected manually every month with less than 31 days.
4. Annual calendar: is a calendar displaying date and month (and sometimes day) that automatically adjusts the date displayed on the timepiece based on 30 and 31-day months. It requires setting the date only once a year, at the end of February.
5. Perpetual calendar: Not only can an affordable perpetual calendar watch do everything an annual calendar watch is capable of doing, but it will also automatically adjust for leap years; there is no need to set it in February. The next time a perpetual calendar will need to be adjusted is in the year 2100.
THE BENEFITS OF SHIJIN CALENDER WATCH
Single Calendar Watches
The simplest and most commonly used of all calendar watches is the single calendar quartz watch. In terms of appearance, the two common types of single calendar quartz watches are the hand type and the window type. The pointer type refers to the usage of hands to indicate the date of the watch. It’s common that there is the large pointer type with an outer ring and the small pointer type with a small disc. The window type has a small window type and a large window with two small windows to indicate the date.
The Annual Calendar Watches
It's the first step toward automated calendar calculations. The display of our affordable annual calendar watch includes day, date, and month displays, and the open window or pointer design makes reading the time easier. Another distinctive feature of the affordable annual calendar watch is that the machine is able to distinguish between the 30-day month and the 31-day month, with the only errors arising from the transition from late February to early March. Thus the annual calendar watch requires one manual adjustment per year.
