this watch is really very nice and accurate. great for those who like electronics. I really enjoyed building it, packaging is included PCB circuit board and all components. thanks to the microcontroller with a 12MHz external oscillator is very accurate! PCB draws its power from a USB port with the included cable. also the alarm function is very useful! you can set 2 different alarms! the shipping was fast.
