Can’t download a watchface

I bought a GARMIN Venu, set it up, down loaded a few apps including the PSX-1 watch face. I just bought a second one and I am wanting to use the same watch face but it won’t let me install it.  It says I can’t install it unless I update my watch through GARMIN Express.  I have not been able to find GARMIN Express.  I tried using GARMIN Connect to do an update but it says there are none available.  Pleas assist.

Sincerely, Byron Nice
