It’s hard to know the right time to upgrade. It’s a question I get a lot, having done this job for as long as I have. It’s the double-edged sword of FOMO: wanting to get your hands on the latest thing as soon as possible, while worrying that next year’s model will just be that much better. The good news is that — more often than not — updates are incremental. Products generally don’t swing radically from one year to the next — that’s not how things work at this scale.

I bring this up right out of the gate because we are presently one year out from the Apple Watch Series 10 (X?). Rumors around the device began swirling well before the Series 9 was made official this time last week. The iPhone X could prove precedence for update, as Apple marked the decade milestone with a radical shift.
