Is anyone experiencing patina?
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”):

Eek that's pretty bad IMO
In this case (pardon the pun) I don't think I can accept patina in this scale
Aaah, I was looking at the dial, not the case! That can be easily solved, I think. [nt]

The issue here is...
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 ? Happy to discuss
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.

Undesirable
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 would discuss this with the AD as in my view it’s not ok
That is really unusual and not normal.
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.
I would not want to be looking at that.
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.
Some gold alloys tarnish like that but it is superficial discoloration and easily removed with a gold polishing cloth. They are usually complimentary at your jeweler. [nt]

Very good.
I’m happy that everyone seems to think that ugly bruise ought to be gotten rid of 
sorry to see that
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 here is something to consider if you're going to polish it off: remember that you can always easily polish it off, but not as easily re-apply it. It takes elapsed time to build up that look naturally... and a few seconds to remove it. So maybe consider if *you* would miss it...

That is not patina. It is tarnish and needs to be removed otherwise it will cause permanent damage. [nt]

So I guess my watch recovered from gangrene
Just back from the RD spa. Thanks everyone
