Hello and thanks for taking an interest in my watch. I am thinning my collection of watches to make room for a new one. This watch is a cool collectors item for anyone who likes the outdoors, vintage watches, L.L. Bean, or just needs a good little field watch. The watch has fixed spring bars and is currently on an original 18mm nylon single pass strap. The watch is small by today's standards, measuring 33mm across. It wears comfortable. I had the watch serviced last year by an avid Hamilton collector and expert. His name is Dan Keefe and he has a website called Hamilton chronicles. He performs vintage Hamilton restorations and maintains an extensive database of Hamilton watch info. The watch is running well and has given me no issues. It winds, sets, and keeps good time. The watch is vintage and as such, I would not recommend swimming or water activities while wearing. It has patina on the dial and hands and the case has a few minor dings and light scratches. Please review the photos carefully as they are also part of the description. Thanks for looking.
