Some very nice choices. I really like that JLC Master Control Chronograph, thats a beauty! Obviously, you have to buy a brand and watch that you are happy with, both interms of functions and what appeals to you. You have some good possible choices in the $5-7,000 range. I can tell you if you tire of watches quickly and like to trade them, stay away from GO and JLC. As nice as they are a friend of mine has a limited edition JLC Master Antoine 8 day reserve, 1 of 200 made in platinum. When he wanted to trade/sell it to buy something else, one place told him they weren't interested in what they called "off brands" like JLC, GO, UN etc. They really focus on buying Patek, Lange, Rolex as they said there is a distinct and strong used market for these brand, while JLC, GO, UN and others you have to wait and hope to find the right buyer. It was a learning lesson for him. In the end it worked out since he decided to keep his JLC, but its quite an eye opener when a place says there isn't much of a used market for fine watches like JLC. It doesn't mean there isn't a used market for them, just that its much smaller and with a smaller audience you might not get as much of your money out of a watch or it might take longer to do so. On the other hand discounts have always been greater on watches like JLC's than Rolex so that might be something to consider.
