Nothing has launched a new smartwatch under its affordable CMF subbrand that improves upon the heart rate sensor, battery life, and GPS tracking capabilities of its predecessor, but gives up on some of its customizability. The Watch 3 Pro is available globally starting today for $99 (currently reduced to $79).The 1.43-inch OLED display provides a ten percent increase in screen-to-body ratio compared to the Watch Pro 2’s 1.32-inch display. It comes in three color options — dark gray, light gray, and orange — but notably drops the Watch Pro 2’s swappable bezel that allowed users to customize the appearance of their watch.The 3 Pro features 131 sports modes, a new four-channel heart rate sensor for better accuracy, and AI-powered coaching and post-workout summaries that offer personalized running plans and fitness insights.Nothing describes the Watch 3 Pro’s new dual-band GPS as “a major leap forward” from the Watch Pro 2, providing better signal stability and precision for “faster and more accurate route tracking in any environment.” The new smartwatch fully charges in around 99 minutes and delivers up to 13 days of battery life “under typical use,” according to Nothing, a two-day increase compared to the previous model. This is reduced to 11 days with heavier tracking, or around 4.5 days with the always-on display enabled.Users can manage the Watch 3 Pro features via Nothing’s X app control center, which has been refreshed with a new UI and supports Strava, Apple Health, and Google Health Connect integrations. Nothing says the older CMF Watch Pro and Watch Pro 2 models will also be transitioning to the Nothing X app.One other gripe, aside from the lack of customizable bezels, is the inconsistent naming between the Watch Pro 2 and the new Watch 3 Pro. This is becoming something of a habit for Nothing’s CMF brand, given the differing format also seen in its Buds Pro 2 and Buds 2 Plus earbuds.
