As someone how change his Apple Watch for a machanical watch and loves his mechanical watch: Yes watches in general and mechanical watches in particular are obsolet beside the aspect of jewellery. They are as obsolet as typewriters or tube television or film photography.

A smartphone or a smartwatch or really any other digital gear does it better. Yes you can use your fantasy and imagine some horror scenarios like nuclear blast or week long power failure but thats not reality: in reality these devices work properly and for the most part you have them in your pocket and use them everyday - so you take all real risks (like hacking or fishing or…) already.

So if you look from a logical point of view there is no place for watches - and don´t argument with the speed or convenienvce: How often do you NEED to know the exact time a day? These 2 or 3 minutes a day make your work not less stressful. And convenience is just an other word for habit.

The emotional point is different…if you want a mechanical watch then by all means buy and use one. But don´t try to justify it with pseudological arguments like it could be a heirloom, the reason “I want to have it” should be enough. You heirs will be much happier if you had the smartwatch and -phone of your dreams than inheriting a 50 something years old watch that they can´t use because the last watchmaker who could service it retiered years ago.
