A big part of that joy, for me, is that this isn’t like anything else in my life, and the difference is refreshing.
Most of my work and hobbies involve technologically cutting-edge digital electronics reliant on complex, inconsistent software, with a typical lifetime of a few years at most. Almost everything else I use and make is effectively disposable.
This is a huge part of the appeal of mechanical watches for me. No electricity. Just mechanics. They’re tangible in a way that software never can be.
For similar reasons, I still read most books on paper.
