Watch winds and runs, but not sure if keeping time, duration of a wind, and chronograph buttons are frozen up. I did dab a little CLR on rusted up button stems, in a attempt to free them, but they are still locked up. Chronograph function can be shut off by moving lever on lower left portion of movement. In addition to the buttons being frozen, there is a bit of rust on levers behind the buttons. Please see pics, they describe condition of the movement well. Watch will stop periodically as well, but i have run it down a few times already. Being sold as is for parts or repair. Movement is marked Transworld trading company 17 jewels. There is some tarnish and grime spots on movement as well. Case is a bit rough, with scuffs, nicks, scratches and quite a bit of finish loss and pitting. Crystal has scuffs and scratches. DIal and hands have tarnish spots and bubbling all over, a bit heavier towards right side of the watch. Case measures 36mm across. Thanks for looking, please ask questions and see my other watch and parts listings.
