Function - This watch is wound by the natural movement of your body. It is recommended to rotate the watch by hand several times to get the watch running before you put the watch on your wrist. The proper motion would be putting your fingers around the outside of the case and twisting the watch in a circle motion, like you would when opening a doorknob.

[All vintage watches are expected to function as described. However, due to age and generally unknown service history (unless otherwise stated), these watches may not keep time as accurately as new or quartz (battery) watches. This is completely normal and does not indicate that there is a major problem. Like your automobile, all mechanical watches will likely need to be serviced at some point in time. Please keep this in mind, as there is no guarantee regarding when these vintage watches may need standard maintenance. Every watch sold by Buying On Time is done so with the expectation that it is not currently in need of service or repair, unless noted. We guarantee that all watches sold are accurately described and in the stated condition when they leave our hands.]
