Like you can see in the pictures this watch was worn quite extensively and it's seen a better times, refer to pictures. It is in a working condition but not checked for timekeeping accuracy or duration. With old pieces like that service is highly recommended, and it's a buyer's responsibility.
All mechanical watches are only wound 3 to 5 times to see if they are working but are not checked for time kicking or duration, same goes for automatics, they are only moved enough times to see if they work.
Batteries installed in watches are not guaranteed, be aware.
