I am seeing the same behavior as well (Card Unavailable - Try again in a few moments). Have tried the following things but none did not resolve the issue:Restart Watch and iPhoneRemove credit cards and re-addReset the watchSign out of iCloud on iPhone and restart iPhone and Watch and sign-in again (with adding credit cards back to wallet)I have now filed a bug report with apple (#37449485), let's hope it will be fixed in the next Beta. Payments working fine in iPhone X with latest Beta, just not in WatchOS 4.3 Beta 2 with Series 0 watch.
