The 3717 is a beautiful watch, I just prefer the more traditional dial and hands of the 3706. I also like the original bracelet they were using on the 3706 more than the later bracelet. The strap for the Exupery is a very nice choice. Far more supple and comfortable than the black croc I had tried them on with years ago. The St. Exupery chronograph is one IWC I wish I had picked up years ago. I've never bought pre-owned. We used to have some great AD's near us and we could get great deals on new Rolex, VC, Cartier, JLC, Lange, Patek, etc. Now some of the dealers are gone, and the discounts are much less. If I were buying pre-owned I would probably seriously look at vintage pieces, as you aren't going to find them new or LNIB. There are lots of lightly used current watches that will save you quite a bit...but make sure you buy from a reputatble seller and that you know what you are buying so you don't get burned. To be honest, most people that worry that a watch will draw too much attention are over thinking how much attention these watches actually attract. Sure if you buy something thats blingy with diamonds, or soemthing that is more than 42mm its going to attract a lot of attention due to the flash or size of the watch. Rolex , IWC, they are not that big of a deal to anyone unless the people are into watches. A friend of mine put off getting a Rolex until he was in his late 30s. He always thought they would attract too much attention at work (so he previously bought a Speedmater,a Breitling, and a Zenith thinking they were more stealthy and better for work) . After buying it and wearing it to work, his big regret was not buying one sooner when it would have cost him nearly half of what he paid for it. Also, no one at work cared or made mention of his watch. If you are going to wear the watch to work or maybe with a suit if you don't have a true dress watch...then I'd go for a Sub, GMT, or something other than the current Sea-Dweller, which is so chunky it looks silly with a suit. A Sub or IWC would be my 1st choices out of what you metioned. As others have said about Rolex it does have greater resale value than the other brands you are considering. Quote: I wouldn't ignore a Rolex because of your age. I had an all steel GMT in college, as did lots of other students. Its a nice watch, but its not like having a Patek in your 20s. Also, go try on lots of watches. I have gone to lots of places to trying things on to see what I like, what fits my wrist, and my needs. Most reasonable sales people will expect you may want to try on several watches, read up on them on the net, and maybe come back and try on a few watches again to help make a choice. Very elegant...nice choice!
