I had to get a smaller strap for my Tank Louis. Decided to go with a matte dark green from Cartier. Just a note for anyone with a small wrist. I have a 6.25in wrist. The original strap was way too big. The standard short strap is definitely too small
. This is Cartier's "custom" intermediate size. I still go to the second to last hole but it's a nice snug but not overly tight fit.
