Here we have the Monster of watches - the SEIKO-SRP307J1-2nd-generation-BLACK "MONSTER" automatic from my cherished, pre-loved, personal collection. It has now reached the ‘for sale’ stage of its time with me and being sold to provide me with funds to continue to enjoy the many beautiful watches out there (and because my wife has told me I have to reduce the size of my collection!)

This watch is in excellent condition (9 out of 10) except for a few very light scuffs that occur from occasional wear). No heavy scratches or dings.

The watch is running on point as you would expect from a Seiko.

Seiko Pro Diver Automatic "Made In Japan" Version. It has the new 4R36 auto movement that allows hand winding and hacking seconds..

The new version of the much loved classic. An interesting and unique looking watch.
