Vintage Howard Mens Gold Filled Tank Wristwatch.

This watch appears to be made circa 1920-1930. The crystal needs to be cemented back on the body. Amazingly, the wind up movement was working until recently. There is rust on each of the hands. I observed both the second hand and the minute hand moving. The watch face is stained with age. Don’t know much more about it. Shipping is fixed at $5.95 for the lower 48 states.
