AS 1977

Description

The AS 1977, which was made in different Versions and by different manufacturies (such as the AS/INT 1977-2) or the FHF/INT 1977-4), is certainly one of the best developed ladies` form movements.

It uses seventeen jewels, an Incabloc shock protection and a moveable hairspring stud. As on most movements of that size, only hours and minutes can be displayed.
