I just got a press release from Tokyoflash announcing the ‘world’s smallest LED Wristwatch’. The watch is called Retsu and is from Saishin. As always the time is presented in a quite unusual fashi0n:
Amazingly simple to read, the lights race up to the digit then trail off leaving one light reconfirming the number. This is repeated for each digit to tell the time.
