Our FKM Rubber Strap is built for comfort, durability, and all-weather performance. Made from premium FKM fluoro-rubber, it's fully waterproof, flexible, and resistant to heat, sweat, and UV. The clean dual-ridge design adds a subtle, sporty profile while keeping the strap soft and comfortable for daily wear.
Each strap includes quick-release spring bars for fast, tool-free installation. For certain dive watches, always test spring-bar fit before daily use.

FKM Rubber Watch Strap - Black
A watch strap gets more contact with your skin than almost anything you own. It should be made like it matters. We hand-select leather from tanneries trusted by the world's finest luxury houses — Horween in Chicago, and heritage tanneries across Italy and France. Then we cut, stitch, and finish each strap by hand in our Utah workshop. The stitching, the edges, the feel. Every detail is deliberate, because the watch on your wrist deserves nothing less.

Much better than the strap is came with. Soft, comfy and great looking with my Citizen Promaster Dive.
FKM Rubber Watch Strap - Black
Store owner replied: So happy to hear you enjoy the rubber strap! They are an excellent change of scene for our watches and they bring such a great vibe. Thank you for your kind words!
Well made rubber strap that looks great on my Yema bronze Superman. They reached out to me because I ordered the wrong size buckle to replace the stainless one, which amazed me. They realized it wouldn't fit and asked if they could switch it for the correct size. I'm not seeing that too often in customer service so I was impressed. Shipping does take a bit of time even if it's not a custom made leather strap, so don't be in a huge hurry. However, their products and service are stellar. I'll be back!
