Watch Description

The watch was purchased in March and is a new old stock. Note that the date shown in the photo follows the European day/month/year format.  I would like some additional information on this model, which I'm currently very satisfied with.  Can you tell me what the numbers inside the caseback mean?  Can you tell me what about the case type, and if are there any specific publications or advertisements?   I found some documentation for the movement online.

Thanks for your support.  -  Best regards, everyone.

Welcome and thanks for sharing your great watch. I believe I found it in 1977 Bulova Linebook205. It looks to be catagorized by Bulova as

21573

I believe the number inside the case back indicates the case style.

7775 is the case style model number, used to determine the correct case parts (crystal, gaskets etc).

Can you please confirm if the first digit in the back case serial number is a 5 or S?

E' difficile da stabilire
A me sembra il numero 5 ma potrebbe essere il carattere S.
Cerco di aggiungere una foto, se ci riesco :-D
