StrapHabit FKM rubber two-piece deployant watch strap with quick-release springbars. Available in 19mm, 20mm, 21mm, and 22mm lug widths. The deployant design means that the tail end of the strap is captured and will not flop around. A polished buckle with twin-triggers keeps your watch secure, but is quick to take on and off. A polished deployant buckle is included with each strap. Twelve tightly-spaced adjustment holes mean these straps will fit well on any wrist around 6 to 8.25 inches, and can be finely adjusted to get the perfect fit. The underside of the strap features a recess to keep your wrist cool. The size and a subtle StrapHabit logo are also molded in the FKM rubber.

The deep colors look fantastic! Quick release springbars allow you to quickly swap straps in seconds without tools. These straps are NOT silicone, they are genuine FKM rubber. They feel nearly as soft and flexible as silicone, but are much stronger, and resistant to picking up fuzz, or cracking. In the photos, you can see how flexible they are, and that they can be completely folded without stretching or cracking. Compared to traditional vulcanized rubber, FKM adds increased durability, chemical and heat resistance.
