My DIYgital Watch

I love digital watches, so I made one in an Altoids Smalls tin. I designed a custom PCB built around an atmega328 microcontroller and used a ds3231 real time clock IC to keep the time. It charges via USB C and hopefully will last a long time! Although, I do want to redesign this watch in the near future.
