There are a couple of parallels to be drawn between the Pixel 8 and Pixel Watch 2. One is obvious, the other a bit more subtle. The first is the addition of temperature sensors — though I would argue that the addition makes a lot more sense on a wearable than a handset. The second is the reminder that in mass-produced consumer hardware land, updates are — more often than not — evolutionary.

The past two Pixel handsets were a reminder of the latter. Google swung for the fences with the Pixel 6 and the subsequent two devices have been largely iterative — refinements, if you will. The first Pixel Watch, meanwhile, was the summation of a lot of time and a whole lot of money. Lest we forget, Google spent $2.1 billion on Fitbit and $40 million on Fossil IP (not to mention the various companies acquired by the companies it acquired, including Pebble and Misfit).
