In the midst of one more spending over $900 on a smart watch, I don’t think the majority of ‘techies’ on this forum care about resale value. If you do, then you’re purchasing the wrong watch. Also, I don’t know how much you pay attention to the Used market for Apple Watches, but it’s increasingly becoming more difficult to sell the more premium model, because consumers aren’t willing to even spend over 500 on a titanium model, when they all share the same internals/incorporate the same watchOS.
Even more so, now Apple has that SE Apple Watch, which has an amazing starting price at $279.
