Works with my 920 and Apple watch 1st get. Doesn't always update from the 920 to the Apple watch immediately, but it does. Hours, duration and calories transfer and are transferred.
Idk if you’ve found an answer yet but an app called RunGap does this. It’s the best solution I’ve found. The only thing it doesn’t do is push the step count to the Apple Watch, though the steps will show in the health app. That’s an Apple issue though, I believe.
