User level: Level 1 (4 points)Does fitness calibration data transfer between Apple Watches? I just synced my data with an Apple Watch 12 and want to know if it starts with the fitness calibration data fresh or if it's transferred over from my old watch.

Yes. If you transferred/restored your Apple Watch data rather than setting it up completely as new, Apple says the Watch backup includes Health and Fitness data, including Workout and Activity calibration data.
So your new Watch 12 should have your previous calibration data. You can still recalibrate it if needed—Apple recommends about 20 minutes of Outdoor Walk or Outdoor Run in an open area with good GPS reception.
