I'm sure this has been discussed to death. I use a strap-changing tool. I find that I have to remove the strap, then use two hands. Otherwise, my fingers get terribly scratched up between the lugs. If I leave the strap on, then it takes about 10 times as long to wind the crown. Any better ideas? I'd love to hear them.
Now if only Lange could stuff that 31-day power reserve into this thin case, the winding would be well worth it!
