Seiko Prospex SRP637K1 “Mini Tuna”

A distinctive Seiko Prospex SRP637K1 “Mini Tuna”, a highly recognizable model within the Seiko Prospex collection. Featuring the characteristic Tuna-inspired case, black dial and robust diver design, this timepiece offers a distinctive combination of functionality and unmistakable Seiko character.

The watch is powered by the reliable Seiko 4R36 automatic movement, with both hand-winding and hacking seconds. The case is in very good condition with only minimal signs of use. The original stainless steel bracelet is also in very good overall condition, with a few light scratches consistent with normal wear.

There are some more noticeable scratches on the underside of the case around the lugs. These were caused during previous strap changes and are located on the underside of the watch, meaning they are barely or not visible during normal wear. These marks have been taken into account when assessing the overall condition of the watch.

The watch comes as a complete set, excluding the original box, and includes both the original stainless steel bracelet and original Seiko rubber strap.
