Fitbit's first smartwatch may have been the Ionic, but the company is throwing all of its resources behind the Versa. While the Ionic targeted serious athletes, the original Versa was more accessible in design, features, and price. That combination won over a lot of users, so much so that Fitbit made an even more affordable version with the Versa Lite.

But now the $200 Versa 2 is revamping the original Versa by bringing some special edition features down to the regular model and including all-new ones—voice commands, Spotify playback control, and the like—that Fitbit likely added to keep up with the Joneses of the smartwatch world. Fitbit only added to the Versa 2—it didn't remove anything that was already present in the original Versa. Even so, that doesn't make it a no-brainer upgrade for happy OG-Versa owners.
