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.

Fell apart after a month
Lasted a few weeks. Seemed ok at 1st but then springclips popped out, i think they were a little bit too short. Then the clasp broke off its hinge. Seems very cheaply made and just very poor quality although the strap itself was good. Rubbish

Great replacement strap, almost identical to the original Casio strap. High quality and great value for the price

Didn't last a month
Original strap lasted years, this one broke after just a single month. I'm not doing anything crazy intense, just simply wearing it. The plastic cracked and it broke off barely a month after it arrived. The pins that arrived with it are also too small, fortunately I could just reuse the original pins to put this on with. I did get two at once so if the 2nd one breaks quickly too I'll update

Inexpensive strap that does the job.
The product arrived on time. The holes in the strap were not fully punched through. However, when the strap was used, there was little resistance. So overall an inexpensive replacement strap that does the job.
