Watchmaker premium faces are buggy and laggy on my watch too. I have had a couple times where it locked up Android wear, and I had to reboot the watch. From what i have seen, the more features the watch face has, the less reliable it is. The worst offenders were some Alpina dials that were stunning looking, but would lock up my watch. There was also a Blankpain Bathyscape dial too that was really really bad.
I use the Intellicom faces a lot more lately, its just a more reliable setup. Or I stick with the more simplistic Watchmaker dials.
