I have been thinking about this for a while. But to cut a long story short: I just don't think that in these days of (supposedly) environmental conscience, it is okay to design a watch that is basically limited by the life of its battery.
Yes, it's difficult to make a device small and watertight, and still enable the exchange of the battery. But it's perfectly doable. It's possible on absolutely all Casio watches without much trouble, and that is even true for those solar watches with a rechargeable battery that lasts for a decade. Apple also offer an affordable possibility to have the battery swapped, even if one perhaps gets a refurbished device and it takes them some glue to unstick.
And in times of planned obsolescence this is a paradigm change, I know. But I really don't care.
What do you think?
