In case you have to use radio:

1. BBC World Service on short waves has the coverage for the whole world (I
mean Earth). The GMT signal is transmitted nearly every hour sharp

2. WWV (do not confuse with WWW) station in Colorado and on Hawaii transmits
UTC time signal every minute on frequencies 2.5, 5, 10 and 15 MHz. UTC is
not much different from GMT now legaly known UT1.

3. Many marine radio stations also transmit time signals.

4. Using ordinary civil radio stations is not recommended

On using mu digital watch (I prefer analog watches with hands but they are
much more expensive) which is simple Cassio for about $26:

- after long periods of watching the watch I established that it advances
0.52 s a day. Quite a lot for quartz watch but that's OK (compare with first
Harrison's mechanical chronometer)
- I reset it every few weeks according to BBC signal
- instead of using the alarm for its usual purpose I use alarm settings to
remember month and day I reset the watch. Thanks to this I can easily
calculate the correction  for given day
- my watch has "dual time" which may be set to anything, so I set it to GMT
