I was initially considering a Calatrava 3802 but after some research decided on SS Nautilus and found one on eBay within my price range and despite being assured it was probably a 2000 model the watch maker who is servicing it tells me it is a 1985 model with a 335SC caliber movement and that all appears to be in good order. I am delighted with the elegance and quality of the watch and look forward to it's return when fully serviced. My only concern is that I saw one or two adverse comments on the internet about problems with this particular movement and wonder if anyone has any experience in this regard? In other words is the movement up to the standards of modern movements despite it's age? Thanks
