Honestly, yes. The strap itself is....nice; but the real kicker is the deployant clasp. An OEM one from Breitling is $200, and this one will accept an OEM Breitling strap without issue; so, buy the strap + clasp for $42, go to AD and buy a gen Breitling leather strap, and put it on the clasp and it looks completely OEM. Then use the strap as a backup to your OEM one.
The straps are nice, not 100%; but nice. They don't look or smell like real leather to me though. The stitching is superb, however the size (girth) is actually bigger than the OEM one. I have the brown croc and that's actually what's on it right now as I wore brown to dinner last night. You can really tell the difference on the inside material vs the OEM. The reps have a plastically look to them. All correct markings, however they aren't the same. The markings look pressed on, whereas the OEM look inscribed to me. On the wrist though, you'd be hard pressed to find someone that would be able to call you out on it.
