Hello all, I am crurently eying a BP 5002 from 2002 from a reputable dealer, located overseas. I have not see the piece for real yet. What is making me very suprised is that the window date, located at 6 o'clock, has a golden lining. It is the first time I see such a thing on this model. Can somebody enlighten me? The watch is supposedly from 2002, non-transitional with the original fish crown. Do anybody know if early series of the 5000 caliber are less prone to beating fast, as it is an often reported issue with this movement?

Hi Fabrice, I've seen the 'golden' window before in some early 5002s it is something that can happen over time - it just needs a servicing to restore. Good luck and make sure you are careful and 'buy the seller'. Regards, Thang

Hello Fabrice,
I have tried to find a photo of my early 5002 and see if the 'golden lining'...........................
It doesn't seem to be the case on my BP.
I never had any issues with the timekeeping on my watch. For the age of the watch it is beating consistently at -11 sec/day ("consistently" being the important word) and I am happy with this until it's time for a service call!!!!
I must echo Thang's words and wish you luck and "buy the seller"!!!

Thanks a lot for your answers! Does anyone know if the golden lining is the mark of a very early serie of the 5002? Do you think it makes the watch somehow more valuable? Nad, it is quite surprising that your BP is running slow. I thought all caliber 5000 were running fast, up to +10 sec/day? In my case, accuracy is the last thing preventing from pulling the trigger, as I am used to Panerai-type accuracy.... I am afraid I will have a hard time living with a watch gaining (or losing!) 10 sec/day! I may have to ask the seller to run an accuracy test for me.... Cheers F

To the naked eye my slow beat 5002, one of the earlier ones, does not a golden date frame. It appears more like a SS frame. In close up shots, however, it looks golden, but I think that is a function of the lighting and maybe some discoloration over time.
It is not golden as seen here,
But it does look that way close up. You can see the pitting in the frame which can refract the light and change the apparent color to the eye.

hi fabrice, i've heard further from a friend who had the yellowing of the window. he wrote: "If it's a 5002 then It's because of the crown - sealants no longer working allowing moisture discoloration as vapour enters-- he will need to send it in for servicing: change his fish crown and get the dial replaced or maybe the window frame plated."

hope that's helpful.

Now that would be a useful feature to know and use if only it was a feature like date chrono or PR. But I suspect that it's a byproduct of the failed seal.

From about one year after the release of BP the window frame of every 5002 received in the UK workshops has had this 'golden' or matt hue to it. Although the factory have not confirmed it,nor probably never been asked,we reckon the window is silver or silver-plated(rather than rhodium in the 500402). Silver readily tarnishes to a matt, sometimes golden,finish. This has nothing to do with the water-resistance of the watch or quality of manufacture but is a natural ageing. It is routine in our workshops to remove the tarnish during service,restoring the original shine(a 5 second operation) but I have noted that watches returned to Schaffhausen for repair don't have the tarnish removed as part of their service. They may prefer the client requests this. Leo
