The watch is working and keeping a pretty precise time, but as for any other used or vintage watch, a basic revision is recommended.
The article is sold AS IS – any other parts that are not mentioned in the description, or not visible in the photos, are not included with this item.
Most of the watches that I am selling are liquidation or collector items, therefor I make no claims and give no warranty regarding continual accuracy of time keeping. Used, antique or vintage watches may need servicing, even if they are in good running condition. Unless otherwise stated they may need to be cleaned, oiled, adjusted or timed. I cannot guarantee a used watch to be waterproof or water resistant.
