Just got some “bad” news regarding the addition of faces for the KW88. I do hope that all the techies here manage to figure this one out and finally give us the luxury of loading all these great faces that have been already created by many in this community. Cant wait to get some tag faces on this watch. keep up the good work guys and gals cause I really don’t wanna spend $1500 for the tag connected 
I would rather spend $3500 on the caliber 16 (actual watch).
I think there is a firmware in development which will fix this. Please see posts from @Pablo_Eleven_Pablo11
I think it may be possible to rip the launcher from other round smart watches and side load it on these watches. It should allow the use of custom watch faces.
No - 4.4.2 = different coding and framework. The ODM is working on it. We will get there in the end. Please be patient or you will be re-flashing your watch and praying that it comes back
