The ZTE Quartz doesn't come with a lot of watch faces preloaded and they might not be your style. Thankfully there is no shortage of watch faces for Android Wear. Here's some to get you started. These should all be compatible with all of Android Wear 2.0's new features.
This developer has a long list of faces which are very customizable but requires in app purchases.
Unsure if these support AW 2.0 features but they still work and look good
When it comes to paid watch faces I find it makes the most sense to buy ones with tons of presets and a community. Those are usually a little more expensive but when you have hundreds or thousands of faces to choose from it's worth it. There are still plenty of cheaper faces out there though. Here are some of my favorites that offer communities and lots of presets.
Offers a free version I believe but I bought it before they offered that so I'm not sure of the differences.
There is a free version of this one as well but I've never tried it as I bought it before there was a free version.
If you're wondering where to get presets for all of these then start here.
