WTB: 1980 Blue Tudor Submariner No Date

[Marshiki]

Hi,

I'm actually not sure if the watch I'm looking for exists (I haven't been able to find one photo online).

I'm looking for the following:

- 1980
- Tudor Sub
- Blue
- No Date

I'm thinking a Tudor with all the above doesn't actually exist (maybe a transitional year and they were all made with dates?). But on the off chance it does exist, feel free to educate me and/or offer yours up!
