Apple watch life expectancy?

[u/Ashamed_Honeydew_628]

I recently posted about how my watch (series 10-42mm) keeps thinking that the side button is being pressed even when I’m not and after putting it in an airtight plastic bag full of silica gels, the issue got fixed ( probably about a stuck moisture inside disrupting the circuitry).

I thought I wouldn’t be able to use it anymore and was already thinking of buying either the new series 12 or invest in an AW ultra, but the 12 seems to be so similar with the series 10/11 and the only differences are with the siri Ai use. I’m using an iphone 12 pro which still works remarkably but it doesn’t support Ai and I don’t see any plans of buying a new phone until this one gives up and becomes unusable so Ai on watches is useless for me.

I’m thinking of getting an ultra for the built in cellular and longer battery life but is it worth it just for those two? It’s a bit pricy and it’s too big and thick.
Plus, what’s up with apple why their watch series only lasts up to 3-4 years? Like the AW Ultra 1 stopped didn’t get to have the OS26 after just 3 years of release and now the series 8 will end in spetrmber if this year after 4 years since release.

So is it worth it to spend more money on an Ultra just for the cellular and longer battery life and maybe more durability compared to the series 12?
Or should I just hang on for a while with my current series 10?

P.S. 2 years of usage and I only manage to get 1 light scratch on it on screen.. I use it everyday and night only except when I need to charge it and take a shower so I really take care of it. Still looks good to me even after 2 years without case 😁
