Breguet

So I recently acquired a 3137 (presumably in yellow gold, but I'll go into this later) and a 3337 in rose gold. I then brought them to Breguet in Switzerland for servicing. After a couple of weeks, I received the estimates, and the one for the 3137 stated...  

I swear my RG ALS was looking more YG to me over time…

One of which was a lightly worn Rolex day/date belonging to my wife. It changed in less than a decade and she was very upset. I, on the other hand, felt it looked quite nice as I dislike the Rolex rose or everose or whatever they call it. Other watches th... 

As I mentioned above, my wife's Rolex changed and it was 100% uniform including the bracelet. It looked beautiful to me but she insisted she wanted to send it to Rolex to see if something could be done. They told us they could apply some sort of coating t... 

I've uploaded another picture in this thread with a true yellow gold Breguet next to the 3137 and I can now see the difference. It's darker and I really like the color. It's so unique.

As you know the new Rolex alloys promise never to change.

I'm still learning with mine!

And that's coming from a guy who's been married almost four decades...😉

but this is completely true, I have a new, unused Rolex DateDay 2019 in its vacuum plastic case in the safe, I have never used it and it is in Rose Gold and currently it is already seen in yellow gold, I must To say that it is not completely yellow, it is... 

Can't say too much based off a single photo. Maybe with more photos and in different lighting (normal light, fluorescent light, etc.). But I suppose it is possible that Breguet is correct, and it's also possible that Breguet is mistaken!

Seems like Breguet's people might be right!

These other metals are what give the gold its necessary hardness, and also affect the color--leaving us with a shade of yellow, honey, pink, red, white, or grey (although older white gold alloys were sometimes plated with rhodium as well). Different alloy... 

I'm also a fan of gray gold but I think yellow/rose gold pieces are so classic Breguet and they also look better on the wrist. I won't have this polished for sure, the color is really unique.

I'm having a watch made with a case of this alloy and I'm looking forward to it!

The colour change is due to oxidation, the superficial action of the alloy with oxygen. If the oxidated top layer is removed, all is looking rose again.

...or do they leave all the grime there after wearing (ewwww).

Some companies specify a mix to the point RG almost looks like copper. As a side note, almost got a two-year-young RG Breguet at half off this past week but decided to wait for the H. Moser Streamliner Purple Haze.

...(which I call 'real' gold) is the best gold : )
