I'm looking for an alternative to leather for a semi-dressy watch. I'm not asking about aesthetics or preferences, I just want to know how sturdy Hadley Roma Lorica (without leather padding or backing) is. I can't really tell from looking if the spring bar loops are stitched in place or just glued. I had a watch fall off my wrist because the original strap had just a folded over, glued down loop, and the glue gave out. So, will one of these keep my watch on my wrist? If not, what non- leather alternatives would you recommend, and what do you think of NATO on a semi-dressy watch. It's 42mm with 20mm lugs. Thanks!
