Free shipping! Brand new! Black! Rubber strap for 20mm lug width! Also for MOD! This is a universal rubber strap that can be attached to watches with a 20mm lug width. Photos 5-9 show it actually attached to a Submariner (116610LN) for photography. Of course, I also use it, and it's a very solid and high-quality strap. The size is 20mm lug width, the total length of the shorter side is about 50mm, and the total length of the longer side is 80mm. However, the length from hole to hole for the spring bar, viewed from the side of the strap, is about 47mm for the shorter side and 78mm for the longer side. However, if you have a small wrist, you can cut the longer strap with a cutter, etc., so some adjustment is possible ✨ Two 20mm spring bars and one 16mm spring bar are included. If you need a replacement tool, please purchase the replacement tool separately, which I have listed. Note: For buckles with extension functions, such as the Submariner, cut a notch in the shape of a convex shape as shown in image 6 with a cutter, etc., to match the shape of the strap. Note: It cannot be attached to watches with a 21mm lug width, such as the Datejust 41 and Yacht-Master, or watches with a 19mm lug width, such as the Air-King (14000). Note: The watch body in the installation image is not included. The item to be shipped is only the rubber strap in image 1. Note: It may not fit all watches with a 20mm lug width without gaps. Please be careful. This is not a Rolex product, so please be aware. How about it, those who like Rubber B? Thank you. Color: Black Management model number: Rubber B x b-line without
