Roger Dubuis

I’ve started developing patina on my H40 over the last few years.. I am a bit in two worlds with the patina. Is this a good thing or a bad thing ? Would love to see photos of your patina’d Roger Dubuis Hommages. Here’s mine (beside her “husband”): Cheers ...  

In this case (pardon the pun) I don't think I can accept patina in this scale

Is patina on the case something undesirable or desirable? To that I can say there are mixed views on that. Secondly should it be removed, will this devalue the timepiece ? Patina is a natural occurrence, so any interference could be seen as negative ? Hap... 

I have the same experience for some of my gold watches. You could easily polish it away using a gold polishing cloth like Towntalk. Hope this helps. Best regards

I agree with one of the earlier replies; it looks more like oxidation then anything else. It can happen if it’s stored in a relatively dark and moist box with little or no air ventilation. You should be able to polish it with soft cloth. If it persists I ...

at first I was afraid, I was petrified... but then I learned to embrace the patina... Some time back my great grandfather's silver alloy pocket watch came to my possession... lots of `patina` from oxydation. A light polish and it comes right off... BUT he... 

...but the patina looks excessive.

Something like a Cape Cod cloth would do it, I’m sure.

Not as serious as some might think..

Just back from the RD spa. Thanks everyone Best Gatsby ...  

The patina was interesting, but on this watch I like it much more factory fresh
