As always, Nicolas is correct. Thought I would give you my 2-cents worth, too:
WARNING: Straps are addictive! You can't have just one . . .or even two or three . . . or ten!
I swapped out the bracelet on my 113 a year ago, and now I must have 30-40 straps. Matter of fact, I've changed straps so often that I wore out the threads on my screws (see my prior post, "Hello all, Newbie with question here"). Easy fix: I ordered more screws (and another strap to boot!).
Have fun!
