An annual/perpetual calendar wrist watch usually is recognized by its watch dial. In general, the watch dial has three watch hands to display the minutes, hours, and seconds. Besides, there is a
calendar window on this watch dial to display the date, month, and even year.
SHIJIN CALENDER WATCH TYPES
Affordable Perpetual/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 a perpetual calendar 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 watch 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.
Perpetual calendar dive watch
Since the annual calendar could not recognize leap months in leap years, the more complex perpetual calendar appeared. Affordable perpetual calendar watches are more difficult to design because of
the problem of dealing with leap year dates, so many models also feature leap year displays.
CALENDER WATCH WORKING PRINCIPLE
The calendar mechanism of all pointer watches, whether mechanical or quartz electronic, is linked to the hand wheel system of the base movement; the calendar mechanism of digital quartz electronic
watches is realized by a multi-functional integrated circuit.
The calendar mechanism of the early pointer watches used the pointer indication type, while the modern calendar watches generally use the window digital display type. There are two types of
transmission mechanisms for changing the date: the crawl-jump type and the instant-jump type. The transmission process of changing the date is done gradually. This mechanism is simple in structure,
reliable in operation, and accurate in jumping. The process of changing the date of the instantaneous jumping mechanism is completed instantaneously at 12 o'clock midnight, and the incomplete
numbers will not appear in the calendar window.
PERPETUAL VS. ANNUAL CALENDAR WATCHES
The most important and obvious difference between an annual calendar and perpetual calendar is as follows. A watch with an annual calendar must be manually set once a year, while the perpetual
calendar does not. The annual calendar is automatically adjusted following every month with 30 or 31 days. However, it must be manually set every 1st day of March because the annual calendar does
not recognize that February only has 28 days, or 29 days for leap years. As a result, the annual calendar must be manually set once a year, while the perpetual calendar does not have to be reset.
With a combination of difference levers and movements, the perpetual calendar will automatically change to the correct date, including from February 28th or 29th to March 1st.
