If you need a digital watch there are numerous options that you can for little more than $10, some which even include the data or a calculator! On the other hand, your smartphone has this functionality built-in, so how your watch looks, and that it’s able to give you the time more quickly than pulling out your pocket computer are what matter in a timepiece.
For something that shows off your love of circuits with several components visible on the face, and displays the time in bright LEDs, the DECKO LED watch is a great option. It’s awakened with a double tap or by turning it, and when active it displays time by sequencing the LEDs clockwise from the 12:00 position to indicate the hour and minute.
It can be purchased as a complete watch, or if you prefer it’s available as an assembled circuit board only. Battery life varies from around 6 months to over a year depending on how much you check it, and if you’d like it to exhibit different functionality, the board has 5 contact pads to program its SAMD21 chip. Re-programming is mostly unsupported though, so you’re on your own if you go that route!
