To wind the watch from an empty state to full, you will need approximately 30 turns of the crown. (Most other hand-wound watches require 40 or more turns, so this movement needs somewhat less.) Once fully wound, the watch boasts an average power reserve of around 36 hours. It's crucial to exercise caution during the winding process.

For those who use the watch daily and wind it consistently, such as every morning, a slight variation in the number of turns will not significantly impact the overall power reserve, as it will be well below the maximum of around 36 hours.

Some users have reported that 25 turns are sufficient when winding every 24 hours. This seems logical because the watch would not need a full wind after 24 hours. Nevertheless, individual preferences may vary, and most owners develop a sense of the optimal winding routine within the first few days of ownership.

Above all, it's crucial to emphasize the importance of not overwinding the watch, which could lead to locking up issues or, worse, damage or breakage of the mainspring. Adhering to the recommended winding procedures ensures the longevity and proper functioning of the timepiece.

Note: Overwinding occurs when a mechanism is wound beyond its designated stopping point, posing the risk of damage or destruction to the winding mechanism. It's important to note that overwinding is a concern primarily for manually-wound watches, not for their automatic counterparts, which normally cannot be overwound.
