When did case # stamps begin?

When did Bulova start stamping the case number on the inside of the case back?

Hopefully someone knows the exact year but i believe it was sometime during the early 1970s. .

I have the 1974 Case Parts Catalog with hundreds of cases listed.  I have no proof just guessing mid to late 1960's?   But would like a more definitive date.

A funny quote from the Catalog: "There are a very small number of old unnumbered cases which are still in the field. If you receive one, and can't identify it properly, forward it on to the case department."

I guess I just happen to have a very small number of the very small number still in the field with unnumbered cases!

Wow a small number being everything made between 1920s and the 1960s. That's no small number!! :-)

The 3 to 5 digit numbers are normally engraved or stamped in black ink.

Didn't they start stamping the case#'s in ink in the late '50's, early '60's?

Okay, so no easy answer.  I guess it will have to be trial and error.  So everyone, open your case backs, identify the year and we'll see who has the earliest model with a stamp on the case!

Caseback stamped 48 (1948).

The inside is ink stamped with the Case reference # 3-67P


It would be interesting to see if anyone has anything dated earlier.

The trouble with the ink stamps are that they wash off at the cleaners....
