If you haven't heard of the upstart tech brand Nothing, it's a UK-based company that aims to make products like cellphones and headphones with innovative features and designs, but at a lower price point than tech giants like Apple and Samsung. Last summer, the company released its newest smartwatch, the CMF Watch 3 Pro, which incorporates AI features powered by ChatGPT, and you can currently pick it up at a major discount.

Originally $99, you can get the CMF Watch 3 Pro for $61.75 at Amazon during the early Prime Day sale—a 38% discount. This is the lowest price this smartwatch has been, according to price tracking tools.

According to Nothing, the CMF Watch 3 Pro is designed for "everyday users and casual fitness explorers." It quickly earned a reputation as one of the best budget smartwatch/fitness trackers of 2025. If you have a Nothing phone, the most noteworthy feature is its direct ChatGPT integration: You can use voice prompts to ask the chatbot questions or set reminders, among other things. Another neat feature, regardless if you have a Nothing phone or not, is its ability to record voices and auto-transcribe conversations or notes with the Nothing X app, which is great for work meetings or class.

If you've used the CMF Watch 2 Pro, you'll already be familiar with the design, which hasn't changed much. It's still got a round display with a rotating crown on the top right, though the display is a bit bigger—1.43 inches compared to the Watch 2 Pro's 1.32 inches. Nothing has also kept the auto brightness adjustment, which is determined by a built-in sensor, and dual-band GPS support with access to five satellite systems, providing greater accuracy when tracking your outdoor activities.

The real upgrades come mainly from the software: The Watch 3 Pro has over 130 sport modes, compared to 120 on the older model. There's also AI tracking with personalized workout recommendations in real time. The battery now lasts 13 days on a single charge, which is two days longer than before. It's certainly in the running for the best sub-$100 fitness watch you can buy right now.
