How to Calibrate Apple Watch SE 2
1. Enable Location Services
On iPhone: Settings > Privacy > Location Services > ON
Scroll to System Services > Motion Calibration & Distance > ON
2. Wear the Watch Properly
Ensure a snug fit—not too tight or loose—on your dominant wrist (or as set in Watch preferences).
3. Perform a Calibration Workout
Go outside to a flat, open area with strong GPS signal.
Open the Workout app on your watch.
Select Outdoor Walk or Outdoor Run.
Walk or run at your normal pace for 20 minutes.
📌 Pro Tip: You can break this into multiple sessions. Apple Watch will aggregate data over time.
Resetting Fitness Calibration Data
If issues persist even after workouts, reset calibration data:
On iPhone, open the Watch app.
Go to Privacy > Reset Fitness Calibration Data.
Re-perform calibration workout as described above.
Use-Case Testimonial

Lock watch orientation and workout type for consistency
FAQs
1. Do I need to recalibrate every time I switch phones? Yes, recalibration is recommended after switching iPhones, especially if restoring from backup.
2. Does recalibrating delete my previous data? Only if you reset calibration data manually. Otherwise, it builds on existing motion profiles.
3. Can indoor workouts help calibrate? No. Calibration relies on GPS and motion combined—requires outdoor exercise.
4. What happens if I skip recalibration? Your Watch will try to estimate based on old data, which may result in skewed metrics.
5. Is recalibration required for new bands or wrist position? Yes, especially if changing wrist or band tightness. Recalibration ensures more accurate motion sensing.
Final Thoughts
Calibrating your Apple Watch SE 2 takes just 20 minutes but pays off with more accurate fitness tracking. Whether you’re training, walking for health, or simply closing your Activity Rings—accurate data empowers better wellness decisions.
