The apple watch will allow for contactless payments via apple pay for people with the iphone 5/5s

And it owuld appear that in addition to contactless payments owning an Apple Watch will allow for in-app Apple Pay(ments) too

According to https://www.apple.com/apple-pay/ in-app Apple Pay does not work with Apple Watch.

I've only heard about 5s supporting Apple Pay with Apple Watch.

I suspect that is because touchID is required so no plain iPhone 5 support.

Actually iPhone 5, iPhone 5c, iPhone 5s, iPhone 6 and iPhone 6 Plus can all do Apple Pay with the Apple Watch.
