Yeah that's a non-starter, I don't ever wanna worry about that in a watch. And putting "designed for lifetime" next to it is just hilarious, where are you gonna trek with no water, from bathroom to kitchen ?
If repairability is one of their selling points, not having spare parts immediately available is a big misstep.
Looks like display and battery are “coming soon”, and those are the only 2 parts they have repair videos for as well.
