It has been a long time coming, but I finally am able to offer my own Uncle Seiko version of the classic Tropic Strap. The Tropic was a standard on many of the diver watches of the 1960's and 70's. Here is my version, revamped for a new generation of watch collectors.
This tropic is available in 3 sizes and is made to hold the larger (2.5mm) spring bars, which are included.
One rubber strap, one pair of 2.5mm "Fat Boy" spring bars. If you plan to wear this strap on a non-diver watch, request the custom spring bars when you checkout.
NOTE: the 22mm version has a more robust buckle.
