Oyster Date from 1973 - Correct Bracelet Code

[Sellyoursoul]

Hi all,

I'm new here and hope i'm not doubling down an a previous thread where the same question had been answered already.

I have found a nice 6694 from ca. 1973 Serial is 3421XXX
however am (and already was at the time of purchase)
99% sure the oyster bracelet is not correct:

Bracelet code: 78350 - 19
End links: 557 B
Clasp: 78350 L5 (from 1987?)

Therefore my question:
Which numbers would I have to look for to have the matching bracelet?
Any help or leads would be much appreciated.

Thanks!
