I just hope that it works well, as the add promissed, and that you are satisfied with it.
It is a model that I like very much. But the one you bought is quite suspicious.
The outinde is probably refurbished to look nice and shiny. But the signs of wear on the platines of the movement, toghether with
the corrosion in the case and on the movement retaining ring stand in too high contrust to the frontal appearance.
I really don't want to appear too arrogant, I myself am quite a long way from being what JohnN would call knowledgable.
But if you want my advice: Just don't invest any more money in it. Enjoy it as it is, if it is good enough, or look for another one, if it is not.
