Crafter Blue green FKM rubber band for Seiko 1965 Heritage Diver models MX03-143

The Crafter Blue green rubber wristband MX03-143 is made of pure vulcanized fluorocarbon rubber, which has superior strength and resistance to oils and acids compared to normal rubber. The MX03 rubber also features a cutaway design that allows you to trim both sides of the strap to fit your wrist perfectly. The wristband is also dust-repellent, anti-UV, and hypoallergenic. The metal end link and lock are made of highly durable 316L surgical steel, and the lock has a brushed finish. The lock has several holes for micro-adjustment, so you can fine-tune the fit to ensure that the Speedtimer sits comfortably on your wrist. Suitable for wrists with a circumference of 152–210 mm. The wristband is approx. 3–5 mm thick, 20 mm wide, and the buckle is 18 mm wide. The package includes a pair of replacement spring bars to facilitate installation.
