Okay, whilst away on holiday i have been having a play around with the KW88.
Using ES Explorer, within device/system/app/Watchnew/ i have found an app called Watchnew.apk
I transferred this over to my LG G5 via Bluetooth, renamed it to Watchnew.zip and have been able to extract and view all the files!
There are many many watch faces hidden within the KW88 but i am not sure how to enable them. I could try working on it after i return from my holiday but there maybe someone out there who could do a better/quick job than me?
Here are some images…
