I bought the 20mm version of this strap for a blackout watch, and whilst it looks pretty good on first sight the strap certainly isn't up to the standards of some of the other offerings out there.
The nylon isn't super thin, nor is it really thick. It's a bit lower grade than that you'd find from something like a maratac. The end of the strap is heat sealed though which is good, although after 4 weeks or so it's started to fray slightly. To be honest a thiner strap is fine though, it's certainly very very comfortable, possibly my most comfortable watch to wear now.
The reason I've deducted a couple of stars though is the longevitity of the PVD finish on the metal parts of the watch. My watches get very little hard use, I type on a keyboard most of the day, so I was really disappointed that the central pin in the buckle had scratched through to silver metal on only my 2nd day wearing it. Additionally the strap holder elements are a bit too weedy for my taste.
Delivery was within Amazon's alloted time period, but it was slow at nearly a week from dispatch to delivery. (not that this should detract from a product review - thus I've left it at 3 stars for this).
Next time I'll be looking for a better quality strap I think.
