Seamaster 300 cal 552 - how many turns of crown for full manual wind

bigtriangle68 · Sep 1, 2023

When I wind a 300 with cal 552 auto movement, I don't hear any indication (such has clicking) that it is fully wound. Does anyone know, approximately, how many turns of the crown is needed for a full manual wind on a 165.024?

The mainspring in an automatic watch is not fixed. It slides by friction when fully wounded.
15 to 20 normal turns should do it.

AFAIK you should mainly wind SLOWLY because of the greater gear ratio...
