This is a big, built like a tank pocket watc.h I don’t know the background history of the watch but I confirmed the specs, etc on Watch You Seek forum. When I bought this about 15 years ago it was serviced for general maintenance and cleaning. I carried it for about a month and then stored it. It winds and runs with no problem. The last time I carried it for a week straight it lost about 1-2 minutes a day but otherwise no complaints. The stem sticks a little but I can set the time with no trouble. When taking pics it looked to me like some light dust got in but otherwise looks clean. Not bad for a watch over 100 years old. Asking $115.00 via PayPal, shipping included. Shipping only to the USA.
