Watch Description

1979 Accutron Quartz Day-Date 10k GF case, with helpful NIST pushbutton hacker at 2:00.

NIST feature allowed owners of that period to hack a slow watch to sync with National Institute of Standards & Technology by depressing the pusher when the second hand is at 12:00, causing the hand to double time it until it synch'd with NIST.  If it was 10 sec fast, depress the pusher anywhere else on the dial & the hand stops for 10 secs.

By 1979 we only have model numbers.  I think your watch is a Accutron Quartz "92839" with a replacement band.

Even though the Accuset pusher is at 2:00 instead of 4:00? I find no literature designating the variance of pusher location.

Any idea how it would 'sync with National Institute of Standards & Technology'?

Stephen, I may be wrong, but believe all that synchronizes is the watch hands on displayed time as per set by wearer. The button pusher is the sync.........

When you have the NIST site up, you coordinate with the pusher to correct any discrepancy in late or early seconds by:

3 secs fast: depress the pusher at 12:03, causing the secs hand to pause 3 secs to slow down to NIST time. 

5 secs slow: depress the pusher at 11:55, causing the secs hand to double-time it to 12:05, to catch up to NIST time.

There is no RC communication from the watch (like a Casio, for instance.)
