Yup, but the long-term average will be pretty good -- gain a little in

either one depending on how the circuit was set up).

Maybe, if the wearer maintains a regular schedule. That's a fair
assumption, until the wearer changes their usage pattern, such as
going on a ski trip.

Also, please note that the original discussion was over the accuracy
of a computah clock, not a wrist watch. Unless left on continuously,
computers don't maintain a set schedule. Even so, their internal
temperature is affected by the building environment.

But is there any real difference between a 'quartz' watch and a PC clock?
They both rely on a low cost crystal?
