waterproof Silicone watchband Compatible with Casio Protrek PRG650 600 PRW6600 Men's sports Replacement Strap Bracelet 24mm Quick release Watch Strap

I have now bought two of these straps in black and dark green for my Protrek PRG-600 and I must say I am delighted with the quality of them. The silicone finish is much nicer feeling than the silicone finish of the original strap and more comfortable to wear. Of significant note is that the strap keeper actually fits the strap perfectly when the strap is buckled, whereas the original one was around 2mm too wide and tall and was prone to sliding around as a result. I hated the damn thing! One thing to be aware of is that when I first fitted one of these straps the compass behaved erratically and the digital compass display began flashing. I then recalled a reviewer on here mentioning this behaviour when he fitted his so I tried reusing the original spring bars as he did and the compass worked correctly again. I suspect the spring bars that come fitted to these straps just need demagnetising. They are decent spring bars too so I'd like to use them in future. My Protrek PRG-600 has had new life breathed into it with the use of these straps and has never felt better on my wrist. BTW, I bought the straps with the plain, polished steel buckles, which although lacking the matt finish of the original strap buckle are nicely finished. For under £15 these are great straps. Highly recommended!

Good quality and flexible - durable watch strap almost the same as my original one. Unfortunately the spring bolts aren't removable and you can't use original ones.
