Question: Will an Apple Watch 4 work/pair with an iPhone 6 with IOS 12.4 but no cellular data or service?

I am iPhone with no cellular service. It has all content erased, updated as far as this older hardware can go, and set-up with a new apple ID. But I would prefer not to activate it as that would require costs on top of my Android phone. The iPhone is a device that my wife has abandoned that I am attempting to set up with an Apple watch which, in my opinion, is the best smart watch. I'm aware that I won't be able to see, respond to, or make phone calls, but to have the rest would be great. Is cellular data a requirement for Apple Watch setup?
