Altimeter Apple Watch Ultra

My altimeter was working fine. I recently took a plane trip and now my watch shows crazy numbers. I’m at sea level and my watch shows ~652FT. Anyone else have this problem? Apple support, if you see this, what is a fix?


thanks!!!

Hello jimmy.woods,


This page here can help provide some steps to help with calibrating the Apple Watch and improving accuracy: Calibrating your Apple Watch for improved Workout and Activity accuracy - Apple Support



1. On your iPhone, open the Settings app.
2. Tap Privacy > Location Services. 
3. Make sure that Location Services is turned on.
4. Scroll down, then tap System Services. 
5. Make sure that Motion Calibration & Distance is turned on.
6. Continue with the steps below.


Calibrate your Apple Watch
1. While wearing your Apple Watch, go to a flat, open outdoor area that offers good GPS reception and clear skies. 
2. If you have Apple Watch Series 2 or later, you just need your Apple Watch. If you have Apple Watch Series 1 or earlier, bring your iPhone for GPS. Hold your iPhone in your hand, or wear it on an armband or waistband.
3. Open the Workout app. To start, tap Outdoor Walk or Outdoor Run. To set a goal before starting, tap the ... icon.
4. Walk or run at your normal pace for about 20 minutes.

If you don't have time to finish the workout, you can complete 20 minutes over multiple outdoor Workout sessions. If you work out at different speeds, you should also calibrate for 20 minutes at each of the speeds that you walk or run.
Whenever you walk or run outside using the above steps, your Apple Watch continues to calibrate the accelerometer by learning your stride length at different speeds. Calibration can also improve the accuracy of your calorie calculations in the Workout app, and the calorie, distance, Move, and Exercise calculations in the Activity app.

My Apple Watch Ultra altimeter is 5,000 feet off in Utah. Swimming temporary resets it correctly sometimes, letting the watch drain completely of battery life will reset the altimeter correctly for a few days, but it still goes back to around 5,000 feet offer. Frustrating. There is another thread open here: Apple Watch Ultra Elevation Way Off - I b… - Apple Community
