Crown Winding & SettingWatchmaking & Horology
Map out the mechanical state and winding functions of crowns at positions 0, 1, and 2, including quickset dates and hacking.
Calculations derived from Swiss and Japanese chronometric engineering standards. Always refer to your watch movement user manual to avoid shearing delicate calendar teeth or stripping winding stems.
Quickset Date Correction
Turning the crown clockwise advances the numerical calendar dial rapidly. DO NOT adjust during 9PM-3AM watch time to avoid gear tooth collision!
Crown pulled out to the first click notch. Engages with the intermediate date wheel clutch.
