When manually resetting a calendar, do so slowly. These mechanisms are not made for high speed operation. Winding may be done by turning the crown only clockwise, or by turning it to and fro. Do, however, give an occasional back turn to redistribute lubricants. Hand wind automatics only if necessary.
Hand winding an automatic when it is fully wound is unnecessary and the most likely to cause wear.
Do, however, give any automatic a few turns of manual winding occasionally to redistribute lubricants in the mechanism and seals. Never use force in pulling out the crown. If you feel resistance, rotate it slightly and gently as you pull it out. This will help align the castle wheel and intermediate hand setting wheel. When pushing in the crown, do so gently.
