Nice old Bulova wind up Excellency ladies watch, number on the back, as best I can make out is J163584. Also on the upper back is BULOVA  ??Gold Filled. Can't make out the numbers. The band is broken. I have had this watch running two or three times before today. Those times, the watch ran for several hours, until it ran down, keeping accurate time. Today, it is a little slow to get started. Ran for about 20 minutes, then stopped. I took the back off, the metal back had Bulova Fifth Avenue New York. Bulova Watch Company, was stamped into the back of the watch, along with some other very small print that I could not make out.  I took four more photos, trying to list the original photo, then the blown up photo of each picture that I took, making a total of eight more photos. I sprayed the back with instant contact cleaner, allowed the watch to warm up, put it back together. It is now running again. For how long, I don't know. This watch is being sold as is, no returns, no refunds. The back of the watch is much easier to read, with the larger photos. The three numbers on the back, inside the rectangle, are 6BA, as best I can make out. Also has U.S.A. 21 Jewels A9.
