I own an IWC Fliegerchrono Auto.
Do a search on timezone.com on it and you'll find tons of stuff on the brand. Generally speaking, IWC watches are priced very well, and their watches intended for tne active lifestyle (aviators and divers) are really built to take rough use. Of course, IWC also make dressier watches which are also great in a different way.
If you want a dress watch, look at Blancpain, Jaeger LeCoulter, Audemars Piguet, Chronoswiss, Patek Phillipe, A. Lange and Sohn, Franck Muller, Parmigiani, etc.
As for Rolex, the following is not intended as flame bait. I owned a Rolex Submariner for a while. After I got into watches, it was my holy grail. My first watch was a TAG Heuer. Nice, but not a "real" refined timepiece. I then went for an Omega Seamaster (Bond Watch). I loved it but still lusted for a Submariner. When I'd saved enough money to buy a pre-owned one, I did. Had it refinished at the Rolex facility in NYC. Then, I started reading about Rolex from true watch enthusiasts. I started looking at my watch carefully and also looking at some of the brands I'd mentioned above. I came to the conclusion that Rolex is nowhere near the quality of those other brands. I compared exterior design and finishing. Rolex looked crude next to the Omegas, IWC's and JLC's. I looked at pictures of the Rolex movements side by side with movements from these other watches. The difference was ridiculously easy to see. In particular, look for a review of the Rolex Explorer by Walt Odets in Time Zone. Walt is a master watchmaker and did some awesome in depth reviews of watches and their movements. Walt's expose of the Explorer was a real eye opener and sparked all kinds of "hate" mail from Rolex afficianados.
I'm really not trying to bash Rolex, just open people's eyes. They would be great watches if they cost half of what they actually cost. But then Rolex wouldn't be able to pay for all their advertisements and COSC Certifications. Rolex is really the choice of the watch neophyte trying to make a statement: "I have arrived". If you're considering buying one, please look at it side by side with an IWC or other fine watch. Check out everything: the finish of the SS, the smoothness of the bracelet edges, the way the crystal fits into the bezel, etc, etc. Then, go to timezone.com and do the research.
Please, no flames from Rolex lovers. They have their place in the watch world, just not at the price that they sell for.
As for "should I buy an Automatic or Quartz movement watch?".
Ask yourself 2 questions: am I fascinated by tiny precision machines; and "do I appreciate art". If you can honestly answer yes to these questions, purchase an automatic movement watch.
