FS is a nice used Seiko 6309-7040. The case back is stamped 126262 dating the watch to February 1981. I believe the watch to be correct, although i'm sure the hands have been aged at some point. They match the plots well and overall it has a nice look to it. The bezel is tight and clicks around nicely, no slip. Bezel, dial and crown are original. Comes on a Seiko Z22 rubber diver strap. I was told it was serviced before I bought it, but there is no proof of this, and therefor I cannot guarantee it being waterproof. A quick flick of the case and it always starts up immediately.
