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 ...

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 ...
