10K white RGP with stainless back. By the 1960 Linebook, this appears to be an American Eagle "F". Nice and clean and keeping accurate time as received.
Interesting note: The movement appears to be stamped "N0" instead of "M0". It is the correct movement for the watch, and there appears to be another one in the database that is dated 1960 on the case and 1970 on the 11AF movement. I wonder if this was an error in the movement department stamping line, or just a coincidence?
I'm not sure what to make for the N0 movement stamp. There are certainly a few reason this could have happened, but I guess the question is did someone stuff up the date stamping code or are they simply a later replacement by Bulova when a watch was sent in to be serviced/repaired.
Either way a 1960 Bulova American Eagle "F" is what it is.
