...have I discovered something.
In this thread https://forums.watchuseek.com/f17/i-...4791487-8.html I talked about not finding a spot in my house to sync until I hung it on my inexpensive atomic wall clock. Once it synced, it has been reliably syncing on my arm every night - for about a week now, rain or shine right around midnight (maybe not shine, but clear weather).
Accordingly, I have a theory that may, or may not make sense.
The watches originally synced in Japan (mine was set to Tokyo and synced a month or so ago). Even though I reset the timezone, perhaps it needs a very strong signal to "switch" to a new transmitter. Now that it has "found" the transmitter in Colorado, it can sync with a weaker signal.
I guess there are several alternatives:
1. I'm full of it
2. Makes sense
3. Old news, we figured that out ages ago.
