Don’t they say you cannot over wind an automatic watch. Experts will be along soon.
I had a Fifty Fathoms with 120 hour power reserve and the instructions state normal use should keep the watch going, but to fully wind it you need to turn the crown 105 times. I did that out of curiosity and the thing ran for days on end.
Also depends on what you are doing, sit at the keyboard all day and the charge will be low, wear it with a fairly hectic lifestyle and it should be good to go.
