    Re: Timex Iron Man Watch=kaput
    From: Doug Faunt
    Date: 2020 Jul 3, 12:57 -0700
    My problem with most watches is the number of alarms.  My Timex has 5 and two time zones, one of which is always UTC (which has bitten me in a couple of instances.)
    Some of the new ham radio digital protocols require a high degree of time synchronization, that is usually GPS-disciplined time.   I'll have to poke and see if anyone has done enough of that with the HF or LF time signals.

    The problem with a watch that uses a LF time signal is it only works
    close inshore. It would be really nice if it calibrated itself when
    the signal was available, then when offshore it could give a corrected
    time and an error bar.
    
    Interestingly you can make your own LF time signal
    https://unusualelectronics.co.uk/retired-products/chronvertor/ and I
    was playing with an arduino project that used the GPS time signal to
    calibrate on Oven Controlled crystal oscillator and then broadcast a
    time signal to ships clocks.
    This Chronoverter  is handy to broadcast time formats in particular
    WWVB, DCF77, MSF or JJY radio time protocol.   I never finished the
    project. I was trying to fit a MSF clock mechanism in a broken brass
    clock case. My clock making skills turned out to be worse than my
    ability at electronics.
