I have my dad's Rolex. It's 40 years old. Works fine. But it also ONLY tells the time and the date, and the date will be wrong if you don't stay on top of it because it doesn't know which months have 31 days and which are shorter. It's super cool, though, that this object still works just as well as when it was new in 1978. But I stopped wearing it (and my other mechanicals) all the time precisely because of their limited featureset vs. a good and attractive smartwatch.
