I've been toying with the idea of eventually adding 1 more luxury piece to my collection to bring it to 6 total. I may not be buying in the next few weeks, but I do like having a goal watch in mind to work for. Given my collection, what kind of watch would you add to it? I'm pretty open to options, but I'd like to stay under 15k (new or used) just as a general ballpark. It can definitely be cheaper than that.
