“Purchased for my sub. The holes are just a tiny bit tight for the sub's springbars, but fit okay. The strap is very thick but does not impact the case, which is a known issue in general with straps on Rolexes especially 6 digit models.
Strap is supremely comfortable, smells like dessert, has a tiny bit of stretch, vents well. Not for the small-wristed—you may not have a hole far enough up the strap. My wrist at 7" had 2-3 holes left to go tighter.
Makes a Rolex look nothing like itself if that's ever a travel concern. Wife thought it looked like a cheap children's toy.
It was between this and the tropic strap for me. What pushed me to isofrane was LIW's shipping options (needed it for travel at the end of the week) and the way the isofrane flows out of the lugs. A tropic strap has a kind of flatness to it on the lug end that can look awkward at certain angles.
Will probably get a tropic strap within a month or two anyway, knowing me, but I bet this vents better. That said, the keepers can be a little ornery to deal with—probably the biggest advantage of the tropic.”
