The SB1245O is the oyster bracelet made for the Seiko Alpinist SARB017, a name Seiko first gave a watch for mountaineers in 1959, and it fits the SPB211, SPB155 and SPB491 too. The oyster is the three-link style, built around wide center links, and this Alpinist oyster bracelet is brushed throughout in 316L on solid female end links. Its screw links come out with a small screwdriver and any link you remove can be screwed back in, so sizing your Alpinist Seiko mod stays reversible.
