CMF Watch 3 Pro launch brings a £99 AMOLED smartwatch to the UK

UPDATED · News · 6 May 2026 · MTW News Desk

CMF Watch 3 Pro is the affordable smartwatch story of the week: Nothing's sub-brand confirmed on 6 May 2026 that the CMF Watch 3 Pro lands in India at an introductory ₹6,999, with dual-band GPS, a 1.43-inch AMOLED display and ChatGPT-powered voice prompts. It is the clearest sign yet that Nothing is treating CMF as a serious wearable line rather than a price-cut experiment.

Why the CMF Watch 3 Pro launch matters

The CMF Watch 3 Pro is a £99 UK smartwatch with a £150-class spec sheet, and that is exactly the gap Nothing has been chasing under the CMF brand. The 1.43-inch AMOLED panel hits 670 nits peak brightness with Always-On Display, the body is precision-milled metal and the strap clips on with a quick-release pin. The 4-channel heart rate sensor and dual-band GPS (L1 plus L5) are not features you normally see this cheap. Crucially, CMF dropped the interchangeable bezel design from the Watch Pro 2, a change multiple reviewers confirmed, trading a quirky accessory story for a more conventional, premium-feeling design.

This is also a meaningful Nothing strategy moment. The CMF Watch 3 Pro launches alongside CMF Headphone Pro in India, signalling that Nothing is building a sub-brand that wants its own audio and wearable lines, not just cheaper Nothing rebadges. For anyone who watched the under-£200 fitness tracker market in 2026 consolidate around Garmin, Amazfit and Xiaomi, the CMF Watch 3 Pro is the wildcard that could disrupt the bottom of the price ladder by mid-year.

CMF Watch 3 Pro AI and health features

The CMF Watch 3 Pro pushes harder on AI than you would expect at this price. Voice prompts are handled via a ChatGPT integration, the workout summaries are AI-generated with recovery insights, and CMF advertises real-time coaching for runners as well as personalised cycling and gym sessions. The four-channel heart rate sensor is the part to watch most closely: more channels usually mean better signal quality on darker skin tones and during high motion, and CMF says it has paired the upgraded sensor with improved sleep tracking accuracy.

On the navigation side, dual-band GPS at this price is genuinely unusual. L1 plus L5 receivers should improve accuracy in urban canyons and dense tree cover, the two scenarios where cheap smartwatches normally fail. The wider sensor array also includes SpO2, an ambient light sensor, a 6-axis IMU, stress monitoring and women’s health tracking. Whether CMF’s software keeps up with that hardware over the next year is the open question, and it is the same one we asked when reviewing the Pixel Watch 4 six weeks in.

CMF Watch 3 Pro battery and design

Battery is the spec that decides if a £99 watch is actually wearable. CMF claims up to 13 days of typical use from a 350mAh cell, dropping to roughly 4.5 days with Always-On Display turned on, and stretching to 60 days in power-saving mode. A full top-up takes 99 minutes. Those are competitive numbers and they comfortably beat anything Apple, Google or Samsung will offer at any price. The IP68 rating is the standard sweat-and-shower level rather than dive-grade, so swimmers should treat this as a pool and lap watch rather than a triathlon device.

The 51-gram weight is the other detail that matters in daily wear. A precision-milled metal body usually means extra heft; CMF has kept the weight close to plastic-bodied competitors. The four launch colours (Light Green, Dark Grey, Light Grey, Orange) are deliberately playful and follow the CMF design language. Bluetooth calling and the dual-microphone setup mean the watch can field a call without the phone, with a small speaker handling audio. None of that is new in 2026, but at this price it is rare.

What UK buyers should watch next

The CMF Watch 3 Pro is officially available in the UK from Nothing’s CMF online store at £99, after early-access slots, and the India 6 May launch confirms supply is now scaling up. Early bird sales begin on 7 May in India, with general availability via Flipkart on 8 May, which usually translates to a wider European restock cycle a fortnight later. UK buyers should expect new colour stock in late May. The CMF Watch 3 Pro is not the watch that will replace a Garmin Forerunner or an Apple Watch Series 11 for serious athletes, but it is the watch that should replace any Amazfit or Mibro recommendation in the budget tier.

The other thing worth watching is whether ChatGPT voice prompts on a £99 watch become a real feature or a marketing slogan. The integration depends on a paired phone, so latency and the quality of the dictation will decide if it is useful. If it works, CMF has effectively put an AI assistant on a wrist for less than the cost of one year of Apple Music. If it does not, it is back-burner branding. Either way, the CMF Watch 3 Pro is the most interesting smartwatch launch this side of summer, and it puts real pressure on the rest of the budget market that we covered in the best fitness trackers under £100 guide.

The CMF Watch 3 Pro launch is small numerically and large strategically. Nothing has shown it can ship serious wearable hardware at a UK list price of £99, and the India 6 May arrival proves the volume distribution is now in place. UK shoppers should pencil this in as the new entry-level reference watch for the rest of 2026.
