This request is different than the last one.
The most accurate TCXO watch is about 1 seconds/year, with regular
wear and lots of adjustment. For at least 1 order of magnitude in
accuracy, what can be made/bought given these initial requirements: it
has to run of its own power supply for ~18 hours a day, and recharge
fully at night. the device must be intrinsically accurate without be
disciplined by an external signal, although that could be done at
night. The size and wei8ght need to be pocketable such a a large cell
phone.I am open to all suggestions and more/altered requirements.
