    Hello!
    Can anyone please share the circuit diagram of a simple digital watch and it's components. I want to try making one.

    A watch - as in a wristwatch - usually is a single custom integrated circuit driving a custom LCD. The only way to approach that with commercial parts is with a small microcontroller like a PIC. Old digital clock schematics are a good way to learn what the logic must do to be a clock, but they are not practical for a battery-powered portable device. What is it you are trying to achieve?

    Most use a 32.768 Khz crystal which are easy to come by, a picmicro can run with one on the TIM1 input source for an accurate 1 sec interval basis.

    You realize you are bucking the trend, most favour 500 yr old technology on their wrist.:rolleyes:

    The hard part is getting it to communicate with your phone so you can read your text messages.
