I am selling this used but not abused Seiko 6139-6005 on a Bond NATO strap. It is sitting in my drawer and not getting any wrist time. This is a great daily wearer. As you can see from the pictures the dial has a heavy patina. I don't know the service history but the watch runs well and keep times, all chronograph functions work. Asking 275$ which will include shipping by USPS in the USA. Shipping elsewhere will be at cost. Please fell free to ask questions by PM. Thanks, Joe
