I agree with you that the term Homage has become something broader than it should. There are enough threads on WC discussing it, but IMO if you were to call it a Homage to the Explorer II, than I would argue it is a proper Homage: inspired by something great, yet still unique enough in its own way. I've had both watches for enough time on my writing guarantee you that they are both great, yet completely different watches. At least for me ;)
So I would argue that there are Homages and homages: the firsts are using one or more watches as an inspiration, but deliver something unique with it's proposition.
Then there are homages, which is basically a very skilful copy of another watch, adding little to none uniqueness to the homenaged watch.
You placed the C63 in this second category, and that's what triggered me ;)
But no hard feelings! Cheers, mate 😀
