Go vintage, and I'll tell you why. There is so much less scrutiny AND there is so much more interest in "old stuff" when you encounter a regular civilian. What I mean by that is if you are wearing a brand new, flashy, and shiny modern Rolex this is going to draw more comments of "hey, nice watch." Then you are left with the dilemma of how to respond. Do you just say "thanks" and leave it at that, or do they continue asking questions about it and share how they have always wanted one, or whatever the case may be. The lingering and nagging reality, no matter how freaking awesome the rep may be (50th anniversary SD43 or the latest Cameron Deep Sea) many of the general public will always have a gut feeling about "cheap Chinese knockoffs."
With vintage, it flies under the radar with the average civilian, but with other watch enthusiasts it can draw the right kind of attention. You can talk about the build, you can talk about the history of the piece and what drew you to that particular one. Then you can share details about your build with them. How you tinkered with it yourself, or how you worked with a really cool watch builder wherever, or how you sourced parts for months (or years) to make this build. Honestly, every watch person I have ever talked to and every civilian I have talked to about vintage pieces has always responded VERY favorably when I share that I love vintage watches and I am building up the courage to assemble and build my own vintage watches. I use the vintage auto restoration analogy all the time because I think it is the perfect comparison. Not one person on the planet (besides maybe a hardcore auto show collector guy) would ever fault someone who restored and built a classic Vette using a mix of aftermarket OEM spec parts. They would all say "awesome Vette" and talk about it fondly. I think vintage watches are the same way with everyone except the most hardcore of the collectors. It's for personal enjoyment.
Good luck! If you decide to go vintage, there is no better place to be than right here. The most brilliant minds in the horology world reside here on this forum and they are willing and happy to help in any way they can. I love this place.😀👍
