Images viewed on watch

I was able to make a custom watch face with picture as background using the phone app and transfer it to the watch as a selectable watch face.

I was thinking the same. I assume you are talking about the photos in the message notifications. That would be great.

Also a custom data field that shows the cell phone signal strength just like there is one for GPS signal strength, if that's possible

Correct. I was talking about messages and other notifications.

That data field used to be available on my forerunner 405/410. When you started an activity, it would tell you the number of satellites you were connected to and the strength or some other data for each. it was pretty cool.

Other watches (for example Apple watch) come with this option. It is very useful and I am considering going for one. I like my garmin very much, but I need one which showing the pictures. Are there any Garmin watches to see pictures on it, or update coming?

I guess the Garmin ecosystem & OS is made to draw as little power as possible. Viewing images require some more processor power and this is also why apple watch needs to be charged every day. Different feature set, different market. I'd rather have a longer battery life than watch pictures on my one inch screen watch ;)

It makes sense. Thank you for adding to the conversation :))
