This watch uses an Atmel Atmega88 (Kinda overkill, but was actually easier to use than a smaller package), with a DS1307 RTC and a two-digit alphanumeric display. I could have gone down the smartwatch route, but I've always had an affinity for seven-segment displays and their aesthetic qualities. The plan is to incorporate this into an enclosure of milled mahogany and machined aluminum, with an acryllic protective sheet over the watch-face. One of the buttons triggers the set command, one increments the value, and the other on the pcb toggles between hour-minute and month-day modes. There is a fourth button that will be implemented into the case that will act so that when the watch face is depressed the digits will temporarily illuminate for a couple of seconds, to get maximum life out of the battery.

LED Wristwatch
I wanted to make a small, practical wristwatch that could be enclosed in a "fashionable" enclosure.
