A lot of the higher end Swiss watches have lifetime guarantees, meaning you could even pass it down to your kid and have it fixed for free. The mechanical movements also mean they don't need batteries replaced.
This is a barefaced opposite to the 'Smartwatches'. Next year there'll be an iWatch 2 or something. Next to the smaller issue of charging many people adore these Swiss watches for their ability to 'just work' for decades and decades.
Another thing I guess, is they're likely to retain their value.
