That’s how it starts!
For me, my mechanical watch obsession started when I inherited my father’s mid-70s Rolex. Back then, they weren’t as insanely out of reach as they’ve become; they were a very robust watch that would Just Work for a long, long time, and which looked nice. (Remember, this was only about 15 years after Sean Connery wore a Submariner in Dr No; Rolex was even LESS upmarket in the 60s, which was a time when very few watches were waterproof AT ALL.)
Then the dot-com boom happened, and I had a little money, and I bought an Omega (which I’m actually wearing right now). It’s a late-90s Seamaster, like the one they put on Pierce Brosnan’s wrist for Goldeneye around the same time. (Incidentally, snooty jewelers do not think you are funny if you ask how to make the laser shoot out.)
There are others, too, but the Omega is the nicest one I own. They are all EMP-proof, spring-driven marvels. Most have dates, but none show days or months. I do enjoy that there ARE mechanical movements with perpetual calendars, though, even if they do cost as much as a cheap house.
About 5 years ago, I fell down the AppleWatch hole after buying one to use while running and biking, and finding it so useful that I wore it to the exclusion of all the other watches. I have a nicer Apple Watch now (titanium S6) that I wear MOST of the time, but several times a month I’ll pull one of the others out to wear. With this usage pattern, they’re all “oh, shiny!” to me, too, which is neat.
