Hi everyone, I've been around this forum for few months but decided to create an account today because I need to ask a question.
I just won an auction from ebay, however then sm600 that I won seems pretty weird since it is using front loading case. Here are some picture attached, I dont know if this kind of sm600 exist. Thanks

 

help anyone?

 

I would say that that case is a 165.020 Seamaster Deville one, for an automatic movement.




There were front loading Seamasters 600, ref 135.018, but the caseback was different:



And although the 600 moniker does not often appear on the dial, I have seen several that had it.

(Change the 5 for a 6 in case of a date watch).

 

Thanks for the information dragoman it is really helpful, my last question is if this watch worth usd$280? cheers
