Sony has pushed out a bug-fixing update for the SmartWatch 2, which primarily restores full functionality for custom analogue watch faces. The prior update broke many of the custom watchfaces, where the date would be displayed incorrectly. The new update moves the SW2 build number to 1.0.B.6.32/1.0.A.4.11 and the phone client build to 1.6.23 (from 1.6.22). The update is live right now via the Google Play Store.
Thanks Julian, Rox and theskig!
