Nice old watch in working order and keeping good time but sold with no warranty as I have had no work done on it. 29mm is approximate case diameter plus crown and winder. Nickel plating on case is worn as is strap although both are still quite useable. Screw back says it is water resistant rather than watertight and to be honest I would always keep older watches with old seals away from water anyway. Movement seems ok though with good balance amplitude and it seems to run reliably.
