Watch face on SWIM2 : default face lost...

I downloaded a new watch face from Garmin Connect app on my new SWIM2, but the result was not so good. So I removed this one to come back to the default watch face (original one), But the watch face is now very poor : poor resolution, poor colors, ... It is not anymore the same one as before... How can I come back to the real default watch face of the SWIM2... ?? Help me please...
