you might be better off seeing if you can find a nice vintage rolex. They switceh dover a few years ago to thier own movement (guts). The guts used to be made by zenith but now theya re made entirely by rolex. Apparently the rolex movement isn't as acurate or robust as the zenith movement. As a result the zenith movements one will hold thier value better than the rolex movement ones. So i've heard.
That being said i've ben wanting a stainless(stainless bracelet) or white gold (leather band) daytona for a while. BUT i am slowly moving over to think perhaps i like the vacheron overeseas stainless better
If she has her heart set on ar olex get her whats she asking for BUT there are a TON of very very nice watches of higher quality out thier for the same or less price than the rolex. Granted when your wearing a rolex everyone knows you have a $5000 (at minimum) watch on. The other only people who are into watches will know. Kind ioof liek us with boats.
Most people know a fountain. Those who are "in the know" would take an OL over a beak anyway.
