Watch is running, but all functions are not working properly. Set feature does not work when you pull out the crown. My guess is something is dirty inside contact wise - old  Battery did have some leakage - I cleaned up the best I could on inside a battery cover as well as battery contacts with a Q-tip, and some alcohol did not remove entire case back. Battery cover seal/gasket is missing. Watches sold as is -  See all images closely ask any questions you might have watch does need repair see video band and Crystal all have light scratches.
