Pair of 20mm Spring Bars with Fat Seiko Tips #SB-01

These spring bars have a barrel diameter of 1.78mm, but instead of the conventional tip diameter of 0.7mm (such as on our SDF-178-20 spring bars), these have 1.1mm diameter tips. This makes them perfect for attaching after market straps to your Seiko diver, or other dive watch that uses a spring bar tip of 1.1mm.

Typically, Seiko spring bars have a barrel diameter of 2.5mm, and they cannot be used with aftermarket straps. These spring bars solve that problem. Use for 20mm lug width watches. Sold as a pair.
