Winding a Lemania 2320 based Patek Chronograph
What does Patek recommend about winding a Lemania 2320 based PP chrono movements (like in in 5970, 5070, 3970, etc): (1) wind "up" only until fully wound. (2) wind "up" only until fully wound and at then wind "down" 3-5 times. (3) wind in "up-down" cycles...
