I agree that timezone is a better resource about watch quality, manufacture, and resale value. There are other watch boards frequented by wis, for examplehttp://www.p178.com/http://www.watchnet.com/
That may not be helpful for you on style matters. On a style board, I guess we should talk about style then. In that case you must tell us exactly what you are interested in wearing with your proposed watch.
Of the watches you list, I think only one of them is suitable for formal wear - the Glashutte PanoReserve. I think white gold or platinum would be nice. The Panerai would be the most rough-and-ready of them all, that's an ideal steel watch to wear with jeans. The Royal Oak screams 17 mile drive, and unless you are a golfer, I wouldn't buy it. I don't like the style of the Pateks that you mention, but they are distinctive and appeal to some, and they have mainstream brand name and resale value. If you buy a Patek, no questions asked, no answers needed, much like Lobb shoes, even the ugly ones.
I've always thought your watch case metal color should match your belt buckle, your cufflinks (and studs), your fountain pen, and sometimes your wedding ring. The watch strap color should match your belt color and your shoes. Buy several watches and you'll always have one ready for the occasion. YG brown strap, WG brown strap, YG black strap, WG black strap should cover the basics, I think. Also, when matching, WG==Platinum==Steel==Silver and YG==RG==Brass, unless you are in a different plane of satorial excellence that I can only hope to afford.
Be aware that a big watch means you need to know the wrist circumference for your watch wrist hand for your bespoke shirt sleeve cuff (you are not using two buttons on your cuff I hope). There are ways of cheating sizes with a French cuff depending on your cufflink, so that's an advantage for French cuffs. A big watch means you need thicker padding on your cousu main watch strap, if you are a wis.
P.S. A wis might be considered a Wisconsiner, or a watch idiot savant, depending on the context. That categorization is not mutually exclusive, of course.
