45mm Tissot Chrono XL Leather Strap Chronograph Watch (Anthracite)

Absolutely nothing wrong with quartz watches but I'd say it's a little bit of all of those reasons. Purists will say mechanical watches are all they consider since the design of the movement is what's unique about different watches and what gives value to a timepiece. You can argue that anyone can throw a quartz movement into a watch and it'll just work, (and super accurately too). A mechanical movement can be unique and at the very basic level, takes skill (and art) to design, produce, and fit into a small case (at least initially). That being said, the majority of movements are mass produced and not in-house, especially in the budget/non-luxury range. There also can always be a pride/prestige factor when it comes to something more unique/expensive/traditional/name brand etc.

For me personally, I like the fact that they're all mechanical and self-contained. The general concept of time in general can be pretty thought-provoking itself. Think of the first person to invent a clock. In order to measure time, you need a consistent reference. With quartz, it's relatively simple with a crystal with an electric current from a battery that produces a consistent vibration. With a mechanical watch though, that consistent vibration needs to be created from basically nothing (just metal) and to me, that's a pretty cool engineering/artistic feat. Springs, gears, forks, etc. That's my personal thoughts at least. I have cheap mechanical watches, somewhat expensive quartz watches, expensive autos, cheap quartzes, and some solar powered/Ecodrive watches too. You can get the best of both worlds and get a new Spring Drive too.

Just buy and wear what you enjoy and appreciate it. Not everything has to be about engineering and art, sometimes you just need reliable time (gshock) and other times something that looks good (to you). As with a lot of things in life, other people won't notice or care nearly as much as you think they might.
