I'm so confused by this as I have done the exact same thing and had the complete opposite result.
I found the Omega NATO's to be fantastic quality, the perfect thickness and beautiful to the touch. I've got polyamide, leather backed nylon, polyester and leather NATO's from Omega.
Yes, the leather ones wearing a bit quick, and the polyester ones are probably not to everyone's taste, but the polyamide and leather backed nylon ones are well beyond any other NATO I own, or have owned in the past. They make the Tudor ones look like an eBay $10 special.
I've had my Bond grey/black since they came out (it must be 5 years old, give or take now, I can't remember), and it's had a heap of wear, including in swimming pools, oceans, etc. It quite literally looks like the day I purchased it. It's comfortable, soft, clean and not a loose thread to speak of.
The leather/nylon one has taken over as my daily the last couple of years and apart from some desk diving swirls on the buckle, it to looks like it is brand new. Admittedly, I keep that one out of the pool/ocean, but still, it's handled the years far better than the bracelet has.
I have 3 Strapify NATO's at home and I only ever use one (a particular one) if I'm doing some laps and even then, I hate it. It looks about ten years old and would be lucky to have been worn more than 100 times. It's also had more than a few tidy-ups with a lighter to stop fraying and wayward threads. I always noticed that the strapify were shorter too, which is a pain with larger wrists.
With what you've written, maybe they have changed their supplier of late, but I'm not game to try them again to find out.
