Watch collector/restorer here.
I don't like the huge, fat watch thing either. Nor am I a fan of subdials and other complications for daily wear. And here's the thing: for the most part ostentatiously big, fat, complicated watches are a low-end phenomenon. As you go higher hundreds and then into thousands of dollars, visual complexity shrinks until you are looking at something like a Rolex Milgauss for about $5000. The Migauss is somewhat fatter than I'd prefer because it's very robust -- it's designed for every day use. For dress use, if cost were no object, I'd wear something like a Vacheron Constantin Patrimony, which is 2.6 mm thick and 20.6 mm across. It's small, but the clean design means it doesn't have to be big. For that reason I wouldn't spend the additional $10,000 for the date complication.
Smartphones haven't eliminated the usefulness of wristwatches; they've just eliminated the usefulness of all the gee-gaws on watches for purposes other than telling time. You don't need the day/date complication, and you don't need the stopwatch or countdown timer, that stuff just makes a watch complicated to operate and hard to read. All you need is the hour, minute and second hand. I also make extensive use of a rotating dive-watch bezel for timing things like runs. When I rebuild watches I sometimes replace the face to cover up the day/date complication because it just clutters the design.
That's the problem with watches: it's hard to find a thoughtfully-designed, stripped down watch for under $500. But you can find them. One of my favorite cheap watches is a Casio that costs only $15 on Amazon -- I think of it as a disposable watch. It is very, very cheap in every respect, but it tells time as well as a $5000 Rolex and has similarly clean design. The only changes I'd make would be to improve the lume and remove the day/date complication.
Anyhow, if you showed up wearing a Patrimony I'd be impressed -- not because you spent $12,000 on a watch, but that you'd spent $12,000 on a watch whose value only a serious connoisseur would recognize. If you want to impress the ignorant, go big. If you want to impress the sophisticated, go simple.
