Look like a geek? No problem. This is a binary watch made by Sverd Industries
. It uses a real tiem clock or so called RTC to get the time and a few LEDs to print the time. But the format is binary so you must know how to read the time. As the creator of this watch says in hsi video, on of the problems with this watch is the power consumption. having LEDs always turned on and a microcontroller looping, will definitelly empty the battery, which by the way is a 3V cell one, in no more than 2 days. To solve that, he used the DS3231 real time clock chip that will draw very low amount of current and with the 220mAh battery could work up to 2 years.
