The gear train of the Förster 630 is a very common one, with directly driven minute wheel and a tiny second wheel. The shape of the movement allows a large mainspring barrel and a rather large balance wheel. Both count for better precision and enhanced running time.

The screw balance is unfortunately not shock protected and beats contemporarily slow with 18000 A/h. It regulates a conventional pallet lever movement of swiss type.

This movement can only be identified on the dial side, and the hallmark looks pretty crude.

The Förster 630 has got a rocking bar winding system. The click mechanism is on the dial side and consists of a well made ratched and a spring, which is hooked onto it.
