Thanks, this is a sensible idea.
I think it is worth noting that recording details of watches that are no longer available should be marked as such.
In reality, there are not too many watches available to purchase that are supportable.
I would make sure that you record these key points because:
a) it’s obviously important to know if they are still on sale.
b) it’s very important for people to understand if a watch is supported (this means: reputable brand, firmware is available, etc…)
