Speaking just for myself, even if I thought it'd be worthwhile to plunk down a minimum of $349 on an Apple Watch (or really any smartwatch), I'd wait until at least the second or preferably the third or later generation/revision before doing so because the differences are usually drastic enough that the first-generation looks gimped by comparison. Think iPad 1 -> 2, iPad Mini 1 -> 2, iPhone 2G -> 3G/3G[S], etc. Totally worth it to wait, in my opinion.
