Hi William, inside it says "Pat. June 10, 1924". I know that is just when it is patented but it's all I had to start with.
Ok the carved numbers, even with a 60x loupe were hard to read so will give as close as I can on those:
H5385-5-56W, H86 (0 5 3 , not sure which is that next number) 7-1265, H399-656 A or H.
Other numbers on the watch are : 6APA (arrow) RF5 The arrow is between those pointing up, I think.
MM53 is under the patent date. 0040296 is after "AAA" (which is under Bulova Quality).
It also says Adjusted and I think the letters are AFZUR (close , very hard to make out)
Swiss is over the 15 Jewels and the number 72263 (the adjusted, 15 jewels , arrow etc., and adjusted are on the inside where the gears are. The rest is on the inside casing.
Thanks for getting back to me. Not sure if I want to sell it or keep it yet, it's lovely!
