1929 - 15 Jewels
1935 - 21 Jewels
I have a Bulova rectangle shaped watch with hinged back cover. The serial number on movement is 125568 with a caliber number of 6AF. There is a square on the movement which I think goes with a 1926 date. Also on the movement it reads 15 jewels 4 adj. The serial number on the hinged back is 8561380. It also says Pat. June 10, 1924. Any info on this watch would be appreciated.
Hi AVFD23 If you have or can take some pictures of this watch, you could enter it in the add a watch database and we can try to ID it together. Please and Thanks
My 6AF has triangle date code for 1926 and the case number is 6555539 which I think matches up to 1926.
Bobbee, triangle also means 1936 as would the case serial number begining with a 6, but I would agrre with you in that the 6AF also seems to fit better with some of the 1926 models.
6AF 17j Adj 1936 Square date code from a 1936 Phantom.
11/03/2011 changed database to reflect 7 Jewel also in this movement model along with 15, 17, & 21 jewel.
New update 11/03/2011. Just received new Ladies with 6AF shield datecode which dates this to 1929.
Now 6AF is shown as early as 1930 based on Omega symbol. Originally shown as 1935/36. Updated 7/12/2011
