Well you should try your best to find the receipt so that they can better help you with your insurance plan with them or you could just go there and talk with them, but I think they would want a receipt to better help you. It also depends if it's worth the insurance plan with how much the phone and the samsung watch cost, if you are able to buy another one with your own money then it might not be worth the insurance plan but the good thing about having the insurance plan is that you don't have to worry about buying it again you can just get another brand new one for free.
without the receipt thank you very much for your help
