What is a hand wound (manual) movement?
Unlike automatic movements, hand wound movements need to be wound on a daily basis to ensure it will keep running. Like automatics, most manual wind watches sold at Island Watch have a power reserve of 40 hours, so you can get by without winding it for a day and a half, but, as the mainspring becomes unwound, the movement does tend to lose accuracy. For this reason, it is a good idea to wind it every morning. If it does wind down fully, as in when it is shipped, simply turn the crown clockwise 20 to 30 times to give it a full wind. They crown will stop turning when fully wound.
