26239OR discolouration

I just noticed some discolouration on my 26239OR. This seems unusual to me. I am not aware of gold getting discoloured? I almost looks like a layer of paint has been striped away?

Has anyone else experienced this w rose gold from AP?

Thanks

How long did either of you own your watches? I haven’t seen or heard of this happening, but lines far too new for that to be likely.

About 2 years. My SA took it in and said this isn’t normal. Sent it in for quality control. Will take a month to hear back.

It’s probably some sort of oxidation. Gold Royal oaks tend to oxidize when exposed to water/humidity

How is oxidation rectified?

That sounds strange to me, I would’ve thought Gold / RG should be relatively safe from oxidation or discoloration. Curios what others’ experiences have been like, for those that have a RG AP (RO or otherwise)?

18k Gold is an alloy, so the other metals will react with oxygen

especially if you live in sunny singapore, humidity level is extremely high.

Also curious to what the fix is? I recently saw a 15510or on display in the boutique that had mild oxidation.

I imagine polishing it solves the problem. Same idea as any other metal that reacts.

I had some discoloration on the caseback of my 26120or so I tested lightly dabbing some flitz on the spot and washing off. Seems to work like a charm. I just made sure not to apply enough pressure to disturb the brushed grain of the metal.

I meant having it polished at Clearwater, not doing so ourselves.

It looks like Flitz makes a precious metal polishing creme.
But I’d be more inclined to have the boutique take care of it.

The metals in the alloy can react - particularly RG. I've read that in particular any kind of lotion, cream, perfume etc can really cause discoloration if it sits on the watch
