I just purchased a Vienna regulator and have it setup on my test stand. My question is when does the snail wheel advance to the next hour? The one on the test stand advances just after the hour. I would think it should advance just before the arming for the next hour strike.

Best Regards

Presumably this is not Grande Sonnerie? If it is, the hour snail must advance after the hour and before it strikes the first quarter of the new hour because the hours are struck at every quarter.

If it's a regular striker, the snail advances at the same rate as the hour hand. It should be in position for every strike when it's time for it.
