Rolex is a terrible example. On top of their products aiming to last generations (nobody's going to leave Apple Watch to their grandchildren), they're also well known for not reporting any sales figures what so ever.
Nobody can tell you how many Rolexes there are in total, let alone the sales figures of a specific model of a Rolex. That's partially what makes them so valuable. People usually don't change Rolexes every year when the new model is out.
Changing an Apple Watch/Android Wearable even once every 3-5 years must be the 7th circle of hell for someone like Dieter Rams.
It's incredible how normal it has become to switch out $500-$1200 products at such a cycle. Wasteful, next to no functional gain (certified electro-cardiography being exempt in my books), supporting narcissism...
It's consumerism to the max. We should all take a step back and think about what we are doing.
