Swiss reference 165.020
Introduced in 1964 as a replacement to reference 14905, reference 165.020 is the last of the automatic no-date Swiss Seamaster de Ville references.
It is powered by the 24 jewel Omega calibre 552.
This reference also features special dials.
Here is the dial of a US market ref. KL6292 (goldfilled) SMDV with the well known linen finish but with only one "T" for tritium.
Has a cal 560 and keeps time within few seconds/24h which is amazing for a 60 years old watch...
This is an excellent thread, thanks @PlainVanilla for the diligent work.
I'll try to contibute with an example of the non-mainstream Emir-of-Bahrain watches. This is a 166.020 in pink gold with a 7077 bracelet dated 65-1 (with 4 double expandable links). Case manufacturer is, as expected, Serva S.A. I've included the EoA, which is interesting, because it mentions the bracelet and the metal designation BB which apparently stands for 18k pink gold. (So I think the metal code BG mentioned in the main post could indeed stand for 9kt yellow gold, as explained in the table from the Omegamania catalogue posted by @gatorcpa in this thread).
