A failure with a version that had a known issue years ago that was replaced without issue by the company. None of them have any issues with the current model. Plus, if you're spending $400 to $10,000 on an iWatch, it better work without issue and be replaced immediately if it fails.
Anecdotally, I have lots of friends with failed iPhones and Macbooks. My girlfriend swore Macbooks off after owning the awful white Macbook that had constant motherboard and screen issues and that Apple end-of-lifed way too soon after release because they never were able to release 64-bit drivers for it (seriously... even though it's their own hardware with their own OS). Doesn't mean all Macbooks have that same failure rate or awful product support outside that model.
One thing I have noticed of my friends with fitbits vs smartwatches, they treat fitbits like beater Casio watches and they treat smartwatches like Rolexes. I'm not sure if it's perception of materials or the fact that smartwatches cost 3 to 10 times as much as fitbits. I know I don't worry too much about my Fitbit Surge 2 HR because it only cost me $75.
