Fixture Maker A

Fixture Watch 2

Model number FXA-2

What the published evidence says about this watch, metric by metric. Every accuracy, compatibility and specification fact on a device page links to its source and shows its date. How we grade it.

Earlier model: Fixture Watch 1.

Accuracy evidence

  • Heart rate at rest

    Unvalidated

    No published test we can use yet. That's not proof it's poor, just no evidence either way.

  • Heart rate in steady exercise

    Limited

    Includes evidence on an earlier model, so the tier is capped at Limited.

    1. Evidence on Fixture Watch 1. Shown here because the maker states the sensor and algorithm are unchanged (Fixture Maker A: Fixture Watch specifications, checked ). Evidence carried over is capped at Limited.

      Measured in steady exercise in 32 people, against a reference of ECG chest strap: error of 4.2% (mean absolute percentage error). Meets our threshold.

      During steady treadmill running, Fixture Watch 1 showed a mean absolute percentage error of 4.2%.

  • Heart rate in interval exercise

    Contested

    Good studies disagree here. We show both rather than averaging them.

    1. Measured in intervals in 22 people, against a reference of ECG chest strap: error of 14% (mean absolute percentage error). Misses our threshold.

      In 22 participants doing running intervals, Fixture Watch 2 showed a mean absolute percentage error of 14.0% against an ECG chest strap.
