Smallest mechanical timer known to you

    Dear Mechanical Engineering experts,

    I would like to know how small a mechanical timer you have ever used or seen.

    Sincerely
    Ramone

    the microchips that are timers are tiny. Its the user interface that makes them large. What are you timing and for how long?

    I agree, that is why I have been
    ...cautious
    I feel we all have responsibilities to "control" the amount of "advice" we give
    and this was pinching my comfort zone

    Sorry if i am asking for too much of advice.
    But please do not be mistaken. My question is harmless. I just want to know what are the smallest mechanical timers.
    If you feel that I am asking silly questions, please feel free to tell me directly.
    I am clueless what you mean by pinching your comfort zone.

    I didn't mean to offend you
    I just try to steer clear of topics that can be construed as dangerous
    a mechanical timer can also be a fuse
    and when you as an OP fail to give specific details on what you are doing, it tends to make myself (and obviously others) uncomfortable.

    The smallest, purely mechanical timer I have ever seen was on old warheads for torpedoes. Extremely high craftsmanship in the one I saw. All hand made.
