Designed as a replacement band for the CZ Smart Wear OS watch series from Citizen, this blue silicone strap offers another look for those who want a durable option to pair with their timepiece. Silicone is very durable, yet has a soft hand feel, which it retains whether it is 0 degrees, or 120 degrees. It is non-toxic and hypoallergenic, and is good at not transferring heat. It can easily be swapped out with any of the watch faces and bands in the line, making it a versatile choice to extend the wearability of the collection.
