I can get this watch fairly cheaply.......... actually not sure. R1800 which means nothing to you. Well say 150USD.

It apparently does not have the original crown. (and strap)

Educate me as I am starting my collection. (or guide me away )

 

Do not necessarily want this specific watch, maybe just some guidance with collecting.

 

If you can provide some clearer photos, it would help. Do you have a photo of the inside of the caseback or do you know the reference number that written there? That info will get you started here: http://www.omegawatches.com/planet-omega/heritage/vintage/
Type in the reference number and you should get some info that will help you with further research.
