Crafted from an upgraded Hydrogenated Nitrile Butadiene Rubber (HNBR) compound, the WFL delivers a high-performance feel comparable to FKM, but with superior tensile strength, tear resistance, and extreme low-temperature flexibility.\u003cbr\u003e\u003cbr\u003eDesigned to thrive in harsh marine environments, the HNBR material offers exceptional resistance to saltwater, wet heat, and compression. The WFL retains all the essential features of the original HP series while adopting a classic waffle-style structure and a micro-adjustment system for unparalleled sizing precision.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpring Bars:\u003c\/strong\u003e ISO-rated Japanese 2.5mm quick-release fat spring bars come pre-installed with this strap, making it compatible with Swiss dive watches. The DiveCore HP spring bars have a 1mm tip, slightly thicker than the standard 0.7mm tip.

Known for its exceptional tensile strength and tear resistance, HNBR outperforms standard FKM in pure physical toughness, making it highly resilient against cuts and abrasions. Because its molecular structure is stabilized through hydrogenation, it offers outstanding long-term elastic recovery and maintains flexibility in extreme cold down to -40 °C. Combined with its unparalleled resistance to saltwater, steam, and wet heat, HNBR is an ideal material for high-performance diving straps designed to endure harsh marine environments without compromising on comfort or structural integrity.\u003c\/p\u003e\n\u003cp\u003e• 2.5mm ISO-rated Japanese diver’s spring bars\u003cbr\u003e• HNBR Rubber \u003cbr\u003e• Measures: 82mm \u0026amp; 128mm\u003cbr\u003e• Thickness: 4mm\u003cbr\u003e• Premium Brushed or DLC Black Stainless Steel Hardware\u003cbr\u003e• Adjustable Locking Rubber Keepers\u003cbr\u003e• Fits Wrists: 6.5\" to 8.5\" Keep in mind that the fit may vary based on your preference for a tighter or looser wear. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThings To Know\u003c\/strong\u003e:These straps have extra material around the spring bar (approx. 3.2mm from the pin of the spring bar vs. the typical 2.4mm), which may cause a tight fit with a few select watches. \u003cstrong\u003eFree, easy returns available if it’s not the perfect fit.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:DiveCore watch straps are not eligible as the free strap in our Buy 2 Get 1 Free promotion, but they do count toward earning a free strap.
