(LATEST!) FKM RUBBER- FOR TUDOR BLACK BAY AND CHRONOGRAPH (T-FIT CLASP) NAVY BLUE

Important: Please read the information below and instructions on how to select the correct strap length for your wrist size. Note: Our strap is designed to fit the older Tudor Black Bay 41mm model prior to 2023 (with 22mm lug width) as well as the Tudor Blackbay Chronograph series. For the full list of compatible Tudor models please refer to the "Design to Fit' section below. This strap allows for the use of the original Tudor bracelet's clasp (3 link bracelet). If you have the 5 link Tudor bracelet, the rubber strap will not fit your original bracelet clasp and you will need to purchase the strap with our OEM clasp which is manufactured to the same specification as the original T Fit clasp with rapid adjustment system. We make this rubber strap in three different sizes - 50mm, 60mm and 70mm. You will need to measure your existing bracelet links to purchase the right combination of length to fit your wrist perfectly. The other method is to measure your wrist size and use our sizing guide below. INSTRUCTIONS FOR CHOOSING THE RIGHT SIZE: 1. Ensure your current metal bracelet fits comfortably and the clasp sits perfectly centered on the underside of your wrist. 2. Count the number of links on both sides, including the curved end-links attached to the watch case. DO NOT measure the clasp itself. 3. Match your link count to our size selection chart below No of links Recommended Size 4 Links 50mm 5 Links 60mm 6 Links 70mm Wrist size selection method (good to select a size up if unsure) Wrist size Recommended Size Combination Below 16cm 50mm / 50mm 16 to 18cm 60mm (12 o'clock) 50mm (6 o'clock) 18 to 19.5 cm 60mm / 60mm 19.5cm and above 70mm (12 o'clock) 60mm (6 o'clock) FKM rubber is most commonly used in the aerospace industry due to its improved resistance to UV rays, extreme temperatures, mechanical stresses, chemicals, and seawater.
