FAQ
Best Rubber and Silicone Sport Watch Straps: FAQ
What is the difference between silicone and FKM rubber watch straps?+
Standard silicone is soft, flexible, and inexpensive. FKM fluoroelastomer (also sold as FPM or Viton) is a premium synthetic rubber with significantly better resistance to oils, fuels, extreme temperatures, and UV degradation. FKM straps feel firmer than silicone but are the preferred material for serious dive watches and outdoor use. Most budget straps sold as rubber are silicone.
Can I use a rubber strap for saltwater diving?+
Yes, silicone and FKM rubber are both saltwater-resistant. Rinse the strap in fresh water after ocean use to prevent salt crystal buildup in the buckle and strap holes, which can cause premature wear. Stainless steel or titanium buckles are preferable to plated buckles for saltwater environments.
