This project combines the modern and readily available componets like ATMega328PB uC to work with this beautiful gem of LED engineering - HP 5082-7415 that is unfortuently rare and obsolete. The watch uses popular DS1337S+ RTC IC to provide basic watch features such as:
- Time and date read and write
- 2 independent alarms
- Day of the week
- Temperature read (internal uC sensor)
- Expected 2 years of battery life
- Buzzer
- Rugged contruction
- ISP programming header
It is built from scratch incuding the code based on register manipulation that only uses Wire library for I2C communication with RTC.

This project was fortunate so far to recieve PCBWay sponsorship!
In this revision PCB has been updated for better routing and footprint fixes. If you want to design your own watch visit my GitHub repository for this project where you can find all up to date fabrication files and documentation.
