Does Observatory work without GPS or a phone nearby?

Yes. It uses the last location the watch knows, and everything is calculated on the watch. With no location at all, it assumes sunrise at 6:30 and sunset at 18:30.

Can I set it up from my phone?

Not yet. Every setting is in the face’s menu on the watch, and phone settings are planned.

My watch isn't listed. Is it next?

Owners of other models can ask for theirs, and those requests decide which watches come next.
