This Rollball version II watch band with curved solid end pieces perfectly fit SEI Automatic Alpinist Watch SARB017 and its variants, also fit the new Alpinist Prospex line such as SPB117, SPB119, SPB121 and SPB123 models. 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. This item includes one pair of FAT spring bars (Generic SEI Dia. 2.0mm spring bar) to ensure a more secure connection. 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 thickness. This Rollball version II watch band is a good choice of SEI replacement watch band for your Alpinist SARB017 and the new Alpinist Prospex line SPB117 and their variants.
