I fixed my ~8 year olad f91w with rubber straps
My F91W straps broke many years ago and the thing was just sitting in a drawer. Recently I went to a trampoline park and they give you these bracelets that you keep after... and I had an idea on how to revive the old thing. It doesnt look half bad either IMO.
Thanks to how flexible the whole thing is, it doesnt matter when the bracelet goes all the way down on your wrist and you find yourelf in a situation where you have to tuck and roll. If I were to wear my Casio royale while skateboarding or trampoline jumping the bracelet would slide down and then lock up on my wrist FOR SURE if i needed to roll. Either breaking my wrist or itself I suppose. So this is my new weekend watch now!
ALSO, these trampoline park bands have a writeable NFC tag for some reason. Using an app on my phone I was able to put the Rick Astley song as a youtube link on it. That serves absolutely no purpose but you can probably do actually cool stuff with it im sure.
