Not original but a good strap
The original straps had perished and made the watch unusable. I bought these and had to watch a you tube vid to help me remove and refit the pins. No pins were provided, so I re used the original ones.

Comfortable but with issues
I originally Purchased one of these straps in september 2025 and despite the lack of instructions found it to be easily fitted (thanks to youtube). As I was walking towards airport security this month, I needed to remove it. However, as I was undoing the strap, the buckle, prong and pin dropped onto the floor. When I returned home I re-ordered the same as a replacement, but when I was in the process of replacing it I noticed that the adjustment holes were in fact not punched all of the way through. Upon checking the old strap I saw that this was also the case - my conclusion is that the pressure of the prong on the strap forced the pin out of the buckle. I recommend that if you purchase this product that you have the capability to complete the holes through the strap before hand. despite this I have found the strap to be very comfortable. Because of the bad finishing of the strap's holes I can only award four stars.

Pins for Navza watch strap are terrible
Terrible. I needed to replace the pin on my watch. One of the new pins didn't work - the internal spring was broken. The other barely held the strap to the watch and came loose after a few times of wearing the watch.

No the ing like a Casio strap
It fits but it’s not the correct size for what they advertise. Very thin and narrow unlike the original Casio strap. It will do for now. You pay for what you get. Cheap strap cheap look.
