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.
