In 10 years that Rolex will hold its value, and may even appreciate in value as they often do.
Even a $40 Casio will still be working good as new in 10 years with less than $5 in parts & labor.
Your $400 smart watch will be literal garbage because its battery is nonreplaceable.
This is super dependent on the watch itself, watch batteries aren’t inherently unreplaceable.
If your problem is e-waste, disposable vapes are by far a larger contributor than a single watch that someone will use for years before buying a new one.
My problem isn’t with either. I am just stating that your average Smart Watch isn’t going to be worth anything in 10 years. There is the battery itself, then the fact that software at best is supported for 3 maybe 4 years, hardware support may or may not exist.
They are inherently disposable while a Rolex, and most watches actually are capable, if not intended, to be heritage pieces capable of surviving decades.
It’s not Apples to Apples.
