Exclusive hand-setting mechanism
For the hand-setting of the Papillon, besides the conical winding wheels, Andreas Strehler also uses conical gear wheels for the sliding pinion and the hand-setting pinion. “If you do it, do it right” is what he says. Although the sliding pinion only transfers little energy to the hands wheel, the setting of the time is much smoother. Also, the locking of the two gear wheels is slightly improved.
Another clever solution found only in Andreas Strehler watches is the non-jamming mesh of the hand-setting lever with the sliding pinion. This is achieved by the hand-setting lever slides along a groove on both sides of the sliding pinion like a two-pronged fork. This lead of the lever makes jamming impossible.
All watches by Andreas Strehler have this hand-setting mechanism.
