Seiko Vintage Turtle Jumbo WR Diver's Watch

Getting hard to source highly original Seiko turtle 150M AUTOMATIC ISO Certified Diver's watch. Watch has the Legendary 6309 all jeweled 17J mechanism which are known to regulate to a higher standard than later Seiko production movements. Can't reasonably fault this one. Case has the normal dings and scratches but is much better than most Turtles that I have owned. These are tough tool watches that were worn in tough environments and cases should reflect that. All Serial / Model #'s are intact. Works well and keeps time. Hands may have been replaced at some time in the past but are the correct type. Deep crown thread. Dial and case back marked with SUWA factory logo. A nice example. Appears to have been fully serviced.
