You can eliminate even that layer of "annoyance" by getting one of
Casio's Waveceptor models (it has a built-in receiver that syncs the
watch to NIST/WWV time signals daily ). Mine's served me well for
several years, seems like I paid ~$90 when I bought it.
An added benefit is the "Time Memo" function - press that button from
the Timekeeping mode and the date and time is automatically stored (I
think it holds about 30 of them, more than enough for a series of
celestial sights). And with that you don't even have to remember what
time you started the stopwatch from, either. :-)
