Biwi is a plastics, rubber, and strap maker in Switzerland (they might do more things as well). They will begin using a material known as Kalrez to make watch straps. What is Kalrez? It is an elastomer, which is basically a fancy plastic with some remarkable qualities, and flexibility like rubber. Kalrez is owned by DuPont chemicals and was originally developed for much more important purposes in aircraft. It can flex like rubber, but is not nearly as prone to deterioration as rubber (which comes from a plant as opposed to being a by product of oil refining). Kalrez is also extremely resistant to heat and cold, and highly anti corrosive (resistant to a ton of chemicals and harsh elements). Most important to luxury watches, the stuff costs a lot, about 6000 Swiss Franc per kilo. These qualities together make it prime for use in luxury watches that today often use rubber, but want something a bit (or a lot more) fancy. These new Kalrez watch straps from Biwi are the answer.
