Watch face numbers

Which watch?  Which watch face?  Can you post a picture of the watch face you want to change?

Epix pro 51

Sorry, I can't help you - I have the Epix (Gen2) like in your thread title...

you can only change the coloured parts. its a design feature of the watch face. unfortunately stock garmin watch faces are pretty limited in terms of what you can and can't change, with this being one of the more customizable stock watch faces. For this one you can change accent colour - which will change minutes and accent bars (i.e. the ones between the data points around the watch face) or data colour - which is the calorie bar indicator and the little symbols for steps, floors and sunset.

If you want more customization than this you are going to need to go 3rd party and find a similar watch face (like Infocal) or design your own so that you can change hands/datanumbers, etc etc.

Hopefully not a hijack, but how hard is it to create your own watch face?  I didn’t know you could do that. Is like picking options from a list or do you have to know code and design?

no idea - unfortunately I don't have the time.

Check the watch face threads as one of them includes a person who has built his own watch faces - you could PM them to ask them.
