This Rollball version II watch band with curved solid end pieces perfectly fits Seiko 5 Sports GMT Series SSK001, SSK003, SSK005. The idea of "Rollball" Rally metal watch band was inspired by a famous game - rolling a ball over a "ball-hop" hump that jumps the ball into rings and anchored by SEI Chronograph watch. Unlike traditional rally bangles, this high-end Rollball version II has precise adjustable links details for easy length adjustment. This Rollball version II slightly reduced the thickness and roundness, also had a relatively less modernized design to evoke strong nostalgia. You can now get the retro look of vintage SEI 6139-8020 Chronograph for your watch simply change your watchband into an upgraded Rollball II bracelet. (Compatible with original SEI 18mm buckle, if you want to install your original SEI clasp, please checks the size of your SEI clasp first.) Pairing with Baton double lock buttoned diver's clasp. Baton Diver Clasp was made of solid 316L stainless steel with extra 4 micro holes for flexible fine tune length adjustment. Baton Diver Clasp is ideal for a watch band with a thickness of approximately 3.5 - 5.0mm. Looking for a well-made and sturdy bracelet to upgrade your Seiko 5 GMT, this watch band will be your great choice!
