XGL-731 TIRE TREAD RUBBER STRAPS 19mm, 20mm, 22mm -- V2
[UPDATE: New Version (v.2) which is must softer and more comfortable!]
This is a reproduction of one of Seiko's rarest straps, which was originally available only in 19mm for their 6105 diver. It is wonderfully flexible and comfortable, yet also thick and durable. It measures approximately 130mm for the long end and 80mm for the short (not including buckle). It is the same thickness all the way down without taper. Comes with a pair of 2.5mm "fatboy" spring bars. Available in 3 sizes (19mm/20mm/22mm).
