Hi,

Many thanks to both of you, Steve and Jeff.

Yes, finally I also sold one auctioned at Christie's, so I guess is a correct, albeit unusual, engraving for the case back.

I had seen the pic at Bulang but... my bad... some missunderstanding here but I always thought it was not a serious website. Of course I was wrong, for what I've been checking now.

To find and expert is a very good choice, but unfortunately I don't know no one for these watches.

So I've tried to investigate as much as I could in the many articles or posts provided about faking, "Sinning" or changing parts of these watches and as far as I know I feel pretty confortable with the results, so I may give it a go now these BUND issue is solved.

Anyway, I attach a zoomed pic of the dial, for you to take a look if you are so kind. Very white hands, probably later reluming or change.
