I have a Casio Pathfinder PAW-2000, which syncs to WWVB (and in theory to 5 other reference stations). > As I was sitting outside reading the manual after buying it, I laid it > flat on the table and started a manual sync to WWVB.

In ~Boston, mine syncs at night, and I have been unable to get it to manually sync. At a pub in downton Fort Collins at 1700, it synced just fine :-) > Anyone know what the drift is like in this watch if it can't find the > signal for several days/weeks?

I would hope that the watch would self-calibrate from the daily syncs, and adjust the free run rate accordingly, but it doesn't seem to. I find that when I travel (to anywhere but near CO) it doesn't sync at night. My watch ends up slow pretty reliably, on the order of about a second per week. I haven't measured it precisely, mostly because I don't have a good way to measure from the display. Perhaps I should use audio from the on-hour chime. On mine, syncing can be turned off, but in most places, I suspect you don't need much of a Faraday cage.
