There are some complications that will only work on newer devices. You can always switch it out for a different complication once it’s downloaded to your watch.
I’ve made a few Bronco watch faces for Apple Watch. You’ll need the Facer App to install them but feel free to download them:

If you guys are interested, the HRG eBay Store has the 1.5 kits on sale for 359.00 with free shipping. Ordered mine a few days ago. Can anyone point me to a good install video?
