Reasearch leads me to believe this is a 1939 American Clipper "A". Yellow gold on original bracelet and shows no signs of wear. Case and band are as reflective as a mirror with no scratches, brassing or scuffs. Crystal is perfect. Dial is a bit chalky in appearance, likely from a poorly orchestrated cleaning.
Movement bears both a shield for 1939 and a crescent moon for 1938.
Online auction purchase - it was initially listed as a women's watch (nobody was watching) - $25 including shipping. Inside of back has a jeweler's mark (sharpie pen) indicating the last service was in 2005. Keeps perfect time.
