Lost Apple Watch

I lost my Apple Watch and I figured I could find it by using Find My on my iPhone but it shows the last time it was charged. The date last seen on it says Oct 9, I lost it Oct 10 but I was in another house and it was dead. I don't know if it was on power reserve mode and it turned off. I tired using Find My but it says it's offline and dead so I can't find it unless I'm connected to wifi. It's lost so i can't connect it to wifi, is there any other way to find it, can you guys track it or something for an emergency?
