Available for sale is a "new old stock" Seiko Kinetic Auto Relay men's watch SMA113.  Cosmetically the watch is perfect.  The band is full length and should fit an 8" wrist.  The original box and papers shown above are included.

NOTE:  The watch sat unused for many years and is in need of a new capacitor.  It's an inexpensive part (about $20) and is available online at Otto Frei watch parts as well as on eBay.  Do a search for "Seiko 5j22 capacitor".

Buy it and replace the capacitor and you're good to go. 

Good luck!
