When you have another watch on and linked to your phone? That's not possible with anything native in Apple. Can you please tell us how you have managed that?
And on the flipside, my phone should tell me when the watch is charged!!! (it will only do that if you have 1 watch. Apple hates it when you have 2).
The cheapest M1 Max refurbished available is over $4k … that’s an extremely different price point to OP’s budget I’d guess
