Amazfit Cheetah 2 Pro Review: Titanium Running Watch Tested

...

What it is

The Amazfit Cheetah 2 Pro is the brand's most ambitious running watch to date, arriving in 2026 after a three-year gap since Amazfit last took the running category seriously. Built with titanium and sapphire glass, it targets competitive runners who want premium materials without paying Garmin Fenix or Polar Grit X2 Pro prices. That said, Amazfit has hiked the price by around fifty percent over its predecessor, so this is no longer the budget-friendly brand play it once was. Josh Kerr wore a custom version of this watch when he ran a world-class mile at the London Diamond League, which is the kind of marketing moment Amazfit clearly needed to signal it belongs in serious company.

Key specs

• GPS: Multi-band GNSS chipset with support for multiple satellite systems
• Battery life: Not confirmed from available sources with specific hour figures
• Sensors: Wrist-based PPG optical heart rate sensor for HR and HRV tracking, SpO2 blood oxygen saturation via optical sensor, skin temperature sensor, barometric altimeter for pressure-based altitude calculation
• Display: Not confirmed from available sources
• Case material: Titanium with sapphire crystal glass
• Water resistance: Swim-tested per source review, specific ATM rating not confirmed in available sources

Performance in the real world

The available sourcing here is frustratingly limited. The5krunner conducted detailed testing across running, cycling, and swimming, comparing the Cheetah 2 Pro against Garmin, Polar, and Stryd references, which are credible benchmarks. The specific numerical results from those tests sit behind a subscriber paywall, so the concrete figures on GPS deviation, heart rate error percentage, and sleep tracking accuracy are not accessible from the provided sources.

What is available is the context around Josh Kerr's mile performance at the London Diamond League. Amazfit released lap splits, heart rate data, and cadence figures from that run. The5krunner flagged that one number in the released data does not reconcile, which is worth paying attention to. When a brand releases marketing data from a sponsored athlete and a detail does not add up under scrutiny, it raises a fair question about how the watch's data pipeline handles high-intensity, elite-pace efforts. That is not a verdict on the watch's accuracy for regular runners, but it is a yellow flag worth noting.

The PPG optical sensor on the wrist uses LED light to measure blood volume changes and derive heart rate and HRV data. At elite paces, wrist optical sensors across all brands struggle with motion artifact, so the fact that Amazfit's data from Kerr's race raised a numerical inconsistency is not surprising. For most runners training at sub-elite intensities, optical HR performance tends to be more reliable, but the Cheetah 2 Pro has not yet demonstrated the kind of independently verified accuracy numbers that would let it sit comfortably alongside the Polar Vantage V3 or Garmin Forerunner 965 in head-to-head optical HR comparisons.

The barometric altimeter uses air pressure to calculate elevation, which is the correct approach for altitude tracking during runs and rides, and is standard at this price tier. The multi-band GNSS implementation is critical for a watch positioned at serious runners, and Amazfit has been improving here, but without access to the full review data, a specific meter-level GPS accuracy verdict is not possible from these sources alone.

The titanium and sapphire construction is a genuine differentiator at this price. Those materials matter for durability and long-term wearability, and they signal that Amazfit is trying to close the gap with Garmin and Polar on build quality, not just specs on paper.

Who it's for / who should skip it

This watch is aimed at dedicated runners who care about build quality and want a premium-feeling device that is not a Garmin or Polar. If you are already invested in the Zepp app ecosystem from previous Amazfit devices, upgrading to the Cheetah 2 Pro makes sense. It is also worth considering if you want titanium and sapphire at a price that undercuts the Garmin Forerunner 965 or Polar Vantage V3.

Skip it if you prioritize independently verified GPS and heart rate accuracy above all else. The data inconsistency flagged from Kerr's race is a minor but real concern for accuracy-focused buyers. Skip it also if you rely on a rich third-party app ecosystem, because Zepp still trails Garmin Connect and Garmin's Connect IQ platform in depth and breadth. Triathletes and cyclists who want best-in-class power meter integration or advanced training load tools should look at the Garmin Forerunner 965 or Polar Vantage V3 first.

Verdict

The Amazfit Cheetah 2 Pro is a genuine step forward for Amazfit, with serious materials and serious ambitions, but the fifty percent price hike means it now has to compete directly with established leaders rather than undercut them. Until full independent test data is publicly available confirming GPS and HR accuracy, it is a watch with strong potential that has not yet fully proven itself against the benchmarks that matter to competitive runners.
