Does the GMT-Master IIc have a hack seconds feature for setting the time? I've seen some videos on Youtube that show the seconds hand stop when setting it, whereas others show it continuing to move.
All GMT IIs have hacking seconds, as do the later examples of the GMT I. I believe hacking seconds were introduced in the 1675 model some time in the 70s.
The GMT II has the jump hour feature where you can set the hour after pulling the crown out to the first position - second (and minutes) continue to run in this position, but the seconds hack when you pull the crown out to the second position.
