Borealis Vulcanized Rubber Strap 20mm Orange

I've been considering an "Isofrane" type strap for quite a while for my Certina DS Super PH500M.
I bought both the Borealis version and the 'original Isofrane' straps (in orange to match the dial on my watch). In short, I've kept the Borealis and returned the Isofrane; I rarely use the phrase 'for the money' because I prefer to simply focus on the quality of the item itself. In this case, ignoring the price difference, I found the Borealis simply more 'wearable' - it fits better and feels better, and I prefer the shape/style of the buckle on the Borealis version.
The fact that the OEM Isofrane was nearly three times the price simply sealed my thoughts that the Borealis was the right choice.
Now my only challenge is showing the fortitude to hold off on buying all the other colourways.

Already had the blue version of this strap for my Citizen diver, and the black one for my other Citizen diver. Like those, the quality and look of this strap is excellent!

Bro forget other iso straps. i own both and i can say that this is the better strap irrespective of price. It just wears better.

Very comfortable strap. My watch has green tritium indices and an orange index marker at the 12 o'clock. In low light the orange strap really sets off the orange glow of that index marker. Looks great!

Really cool strap, super soft, no break-in period… and at a very good price too!
