One question: if your Burberry watch goes with everything and you absolutely love it, why look any further for a 7-10k watch? Let me tell you, buying a 7-10k watch will not stop your addiction. If I were you I would put all my other watches out of sight for like 3 months and just wear my Burberry, then if after 3 months you still HAVE to have a luxury watch, feel free to start thinking about it.
I have 11 watches, both cheap and expensive, (birthday gifts from family, Xmas, etc over the years) and enjoy wearing them equally. Although I wear it almost every day, I do leave my ballon bleu at home sometimes to wear my daniel wellington, or even the watch that my mom bought for me for 60 bucks when I was 16, which at the time felt like a fortune.
So if I were you, I would stop stressing about it. After wearing my ballon bleu for over a year I don't even think about it as a luxury item, it's just my watch, like all 10 others. I just enjoy wearing it because it is pretty, regardless of whether or not it is a luxury item. So for that price point, I would really take it slow and think about it carefully.
Just my two cents, hope that helps!
