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 data-index-in-node=\"0\" data-path-to-node=\"0\"\u003eHydrogenated Nitrile Butadiene Rubber (HNBR)\u003c\/strong\u003e is a premium, high-durability elastomer engineered to withstand extreme physical and environmental demands. 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.\u003cbr\u003e\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 style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eApple Watch Sizing\u003c\/strong\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eSmall Size:\u003c\/strong\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e Fits Apple Watches: (38mm, 40mm, 41mm)\u003cbr\u003e\u003c\/span\u003eSeries 10 42mm, Series 11 42mm, Series SE 3 40mm\u003cbr\u003e\u003cstrong\u003e(20mm band width)\u003c\/strong\u003e\u003cbr\u003e\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e\u003c\/strong\u003e\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eLarge Size: \u003c\/strong\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eFits Apple Watches: (42mm, 44mm, 45mm, 46mm)\u003cbr\u003e\u003c\/span\u003eSeries 10 46mm, Series 11 46mm, Series SE 3 44mm\u003cbr\u003e\u003cstrong\u003e(22mm band width)\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli style=\"color: rgb(0, 170, 255);\"\u003e\u003ca href=\"https:\/\/www.blusharkstraps.com\/products\/divecore-hnbr-rubber-wfl-professional-diving-watch-strap-for-apple-watch-ultra-black\" target=\"_blank\" rel=\"noopener\"\u003e\u003cspan style=\"color: rgb(0, 170, 255);\"\u003e\u003cstrong\u003eShop this strap for the Apple Watch ULTRA.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\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.
