Bulova 1924 153
10A 16 jewels 2 adj ; case 18 KGF ; running strong
EDIT: Updated root record w/ info from Syfre:
side the case :
19 K gold filled (yes 19 ! )
there is also a "coat of arms" (i used google translate for that because i don't know the english word, it's "blason" in french). I don't think this is a bulova case.
The movement is a very nice bulova 10A 16j ; serial number 115595
there is also a symbol for the date code (probably how i dated it)
The dial is a metal dial with bulova on it.
