Ok. I'm sorry but I couldn't resist. Here's the deal. You say you want an exceptional timepiece. Then you mention by name one of the most expensive well-known brands out there, but a QUARTZ movement. That is not an exceptional timepiece. It's an overpriced bit of name brand snobbery. For good measure you throw in a couple luxury brands that "aren't good enough"
Take a look at the next "black tie" event you attend and make note of the timepieces being worn by men and women alike. I'll help you out: It's in bad taste for men to wear a wristwatch with a tuxedo.
If you're truly interested in watches, I would suggest educating yourself on the movements, the engineering and the history of mechanicals. Spend some time on the forums, get some books. Talk to a watchmaker.
If you're just interested in appearances, the most impressive thing you can do with your 50k is invest it wisely. Most of this world is more impressed with someone who can turn 50k into 100k than someone who can turn 50k into some diamonds.
