Recently, we’ve been hearing reports from Twitter and Reddit that the Apple Watch’s plethysmograph sensor plays not-so-nicely with wrist or arm sleeve tattoos. The ink pigmentation interferes with the sensor’s ability to read your heart rate — and with it, the Watch’s ability to assess whether or not it’s maintaining skin contact.
After some brief tests, we’re inclined to agree with those early reports — if your tattoo happens to be a solid, darker color. This is has to do with the way Apple measures your heart rate.
We also found a pulse oximetry sensor when we took apart the Moto 360 — check out the teardown to learn more!
