Here's some useful info about the watches..
* Designer watches
like D&G, Gucci, Dior, Armani are really not serious watch makers and those are trendy one season watches made to last few years. Basically throw-away watches.
* One-word brands (cheaper ones) like:
Casio, Citizen, Fossil, Swatch, Seiko, Omega, Rolex, Breitling, Longines,
* And two-word brands (named watches) that can be VERY expensive like:
Ulysse Nardin, Vacheron Constantin
My advice would be if you're looking to buy descent watch with mid budget go with Longines. Those are really good mid priced Swiss made watches that are made to last and have timeless design. Great quality watch for the cash spent.
If you want to spend few (thousand) bucks more, go with something like U. Nardin or V. Constantin. Those are high end watches that will always cost a fortune.
