Received my pink gold Rolex Day-Date 1803 two days ago. It was sold to me as unpolished and it might even be that. When I unboxed it, it immediately struck me as pinkish at best. It certainly wasn’t yellow gold. If you place it next to a bona fide yellow gold watch you can spot the difference: I remember reading on the forum that pink gold can discolor. I believe it is the copper content in the alloy. I stumbled on this article: https://www.thewatchbuyersgroup.com/why-your-rose-gold-watch-may-now-look-yellow/ Tl;dr? Well pink gold discolors. Rolex has found a cure with their Everose alloy. But the proces can reversed with a polish. However I’m not keen on a polish. But what does a light buff with a Cape Cod cloth do? Let’s take a safe part, the clasp: Ok that works. Does is work on the case as well? I daren’t touch the bezel or the brushed parts Bottom line: I now own a Rolex with one pink leg. Vintage pink gold turns yellow, but it can be overturned. I am now wondering if there is a way of cleaning without having to polish op brush the watch.
