CMF's New Pro Smartwatch Gets Beefier, Healthier, and Less Customizable

The world of cheap Android smartwatches is pretty crowded, but there’s still room for one more if Nothing’s subbrand CMF has anything to say about it. CMF unveiled the Watch 3 Pro today, which gets a little bit of a size increase and some additional health-tracking features compared to its predecessor.

Specifically, the Watch 3 Pro adds a more advanced heart rate sensor into the mix. According to CMF, an optical sensor will be able to glean “finer variations in blood flow,” which should equate to more accurate heart rate tracking. CMF says that, thanks to the new sensor, the readings are up to 7% more accurate while exercising and up to 3.6% more accurate while resting compared to previous generations. Health features this go-around include blood oxygen tracking, stress tracking, reminders to drink that important thing called water, and even guided breathing sessions to help you chill out for once.

In addition to a better heart rate sensor, CMF’s Watch 3 Pro will also get a bigger screen—a 10% size increase over the previous generation. Specifically, the Watch 3 Pro has a 1.43-inch display over the previous generation’s 1.32-inch display. That’s great for anyone who doesn’t fancy squinting at notifications on their watch all day. An AMOLED display should also help make the watch’s display contrast-y and clear. CMF says the Watch 3 Pro’s display will top out at 670 nits of peak brightness. That’s not anywhere near the level of an Apple Watch, but you should expect certain compromises when buying a cheaper Android alternative.

One thing that the Watch 3 Pro won’t have, however, is a customizable bezel. The Watch Pro 2 has bezels that can be changed in and out at will, depending on how you want your smartwatch to look. Not the biggest deal, but also kind of a bummer to see that same freedom hasn’t been extended to its newest model.

Battery life-wise, CMF says its Watch 3 Pro performs a little better than previous iterations. According to the company, the Watch 3 Pro will get a max of 13 days of battery life compared to the previous generation’s 11 days, though that will obviously depend on usage and whether you have the heads-up display activated. Heads-up displays have a pesky habit of killing battery life, since screens are the number one way devices typically eat up juice.

The good news is that the CMF Watch 3 Pro hits an affordable note. While the retail price is listed as $99, the smartwatch is currently marked down to $79. Whether a watch like this is your style is a personal choice, but it’s nice to know you can get in the smartwatch game for not a ton of money nowadays.
