Battery life reaches up to 13 days with normal use, or 2–3 days with always-on display enabled.

While most budget fitness trackers cut costs by dropping the display, the CMF by Nothing Watch 3 Pro takes a different approach. The affordable smartwatch features a 1.43-inch OLED screen and is currently listed on Amazon for $69 across all color variants — a notable discount from its usual $79–$99 retail price, and $20 less than the screenless Google Fitbit Air.

Design Options

The Watch 3 Pro is available in four colorways, each with its own distinct bezel design, detailing, and matching strap. Through the Nothing X app, users can choose from a wide selection of watch faces ranging from information-dense sport dials to clean, fashion-forward styles.

The author has personally used a Watch 3 Pro since picking one up during a similar promotion several months ago, and it has frequently replaced a beloved Casio GA-2100 for daily wear. Battery life has been a strong point — even with always-on display activated, the watch typically lasts two to three days of regular use. One caveat: the watch runs on the larger side, which some users may find slightly uncomfortable during sleep tracking.

Pricing

On a Tighter Budget? Consider the Previous Model

If $69 is still stretching the budget, the CMF by Nothing Watch Pro 2 is currently available on Amazon for just $39, down from $55. While it falls short of the Watch 3 Pro in GPS accuracy, heart rate monitoring precision, battery life, and display size, it runs the same Nothing X app and supports interchangeable bezels for a degree of personalization.
