NOS Vintage SEIKO Black Rubber Dive Watch Strap ZTA05J. 22mm. Bead Blasted Buckle. See last pic of bead blasted (left) vs brushed (right).  New never used

Make sure it will fit your watch before buying. 

Because they are around 20-30 years old, all straps are sold as is. Due to this age, I can not guarantee on how long they will last. 

I have recently acquired a portion of the left over inventory from the House of Seiko watch repair/jewelers in San Francisco. I will be posting many watches, straps, bracelets, parts ect over the next few months. Check my store for more watch related listings.
