The Hanhart 750 is a 19 ligne stop watch movement with a resolution of 1/10 second
and a maximal timing size of 15 minutes.
Its three buttons allow additive timings.
The ring balance is beared in two KIF Trior shock protection bearings (only on the movement side with
a jewel) and beats with 36000 A/h. It controls a pin lever movement, where, unlike on standard pin
lever movements, the fourth wheel is not driven by the escapement wheel, but by another wheel
inbetween. Additionally, the fourth wheel with its center second hand makes two full revolutions
per minute.

On the dial side, there's a slotted lever shift, which is responsible for starting and stopping and
another one for the resetting of the hands. On start/stop, the balance wheel is moved, so that a
reliable start is guaranteed.
