If you want to make your own electronic watch, a RTC module is necessary to keep track of the time, with very low power consumption. This tiny RTC module is based on the real-time-clock chip DS1307 which communicates over the I2C protocol. The clock/calendar provides seconds, minutes, hours, day, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The module can run more than a month with a single CR1220 battery.
