I'm not understanding the downvotes. Pebble devices, as well built as they are, are using components that have definite lifetimes. They are not designed to last forever or be fully user serviceable. What do you do when the components fail?

Components having definite lifetimes and planned obsolescence are two different things, the latter implying artificially limiting the useful life of a product. If that's what you meant, others may be down-voting you because they don't think Pebble in fact did that, especially as you haven't provided any evidence to that effect.
