I can only agree with the previous replies, that patina on the case of a modern reference just doesn't look good, it's a problem that shouldn't have occurred -- hardly something charming.

Hope it will be possible to fix this issue without altering/replacing the case ;-) Cheers.

Is anyone experiencing patina?

 
 By: Mr.Gatsby : August 23rd, 2020-02:32
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 ...  

I just saw! ;) [nt]

Eek that's pretty bad IMO

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... 

Undesirable, for me. [nt]

Maybe oxidation/tarnish, not patina my friend.

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 ... 

That’s not patina....

that’s gangrene!!! 😮

C’mon [nt]

That is really unusual and not normal.

 
 By: jlux : August 23rd, 2020-05:24
I have never seen anything like this on a modern gold watch. It can of course be polished but still ....

Two amazing and beautiful pieces, I especially love that RD a lot

That ,patina, is something i can’t handle 😬 sorry. A nice polish would do the trick i guess

To answer your question; for me it’s a bad thing.

 
 By: Jay (Eire) : August 23rd, 2020-05:55
I would not want to be looking at that.

Very good.

 
 By: Mr.Gatsby : August 23rd, 2020-08:37
I’m happy that everyone seems to think that ugly bruise ought to be gotten rid of

sorry to see that

 
 By: patrickh : August 23rd, 2020-09:45
ask to a watchmaker to look at the calibre as the oxidation is in regard to crown and pushers, IMHO. Cross fingers and keep your watches in a better safe place. Love your Dufourgraph ++++

interesting

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... 

The RD is astonishingly beautiful...

 
 By: mdg : August 28th, 2020-10:51
...but the patina looks excessive.

Easy to remove.

 
 By: ChristianDK : December 16th, 2020-13:03
Something like a Cape Cod cloth would do it, I’m sure.

Mate that’s what I thought so too...

 
 By: Mr.Gatsby : January 1st, 2021-02:16
Not as serious as some might think..

So I guess my watch recovered from gangrene

 
 By: Mr.Gatsby : September 2nd, 2021-15:34
Just back from the RD spa. Thanks everyone Best Gatsby ...  

Just caught this post now, good to have it back to clean condition

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

Which Model is this RD
