Hi John,
The watch is in very good condition as far as can been told by the single picture.
There seems to be a tiny blemish on the originally looking dial - DO NOT touch the dial (under no circumstances)
and leave it as is - it has a very beautiful vintage look with a very slight patina! I would not bother about this tiny mark...
I guess there is not much to do other than a service... so try to do it locally and save
a lot of bucks and - what is more important - very long waiting time - could easily take
1 1/5 to 2 years!! But let us wait for some more pictures after you have received the watch to give you more advice...
It is a nice addition to any collection. I have the larger ref 570 in my collection which has the same case and dial
design but is considerably larger at about 35 mm (if I recall correctly).
Enjoy!
Erich
