I've already developed my watch face and test it on Garmin simulator.
I've some question?
1. How to deploy the watch face on my Fenix 3?
2. How to publish to Connect IQ?
1. You can build the app for a device in Eclipse (Connect IQ menu > Build for Device Wizard), which will create a PRG file. This PRG can then be copied into the /GARMIN/APPS/ folder on the device.
2. To publish to the store, read more here: http://developer.garmin.com/connect-iq/how-to-publish/
