A Stopping Watch

My husband's grandfather passed away a little over a week ago. Ever since the day after he passed away my husband noticed that his watched stopped at exactly 1135 pm. He didn't think anything of it and just fixed it. This keeps happening though every night since he passed on and the watch don't use a battery. It is a wind up watch. So we don't know why it is stopping at that time? We are not sure when he passed on but we got the call at 3am that he had passed on. When we got there he was real cold. I know for a fact it takes time for a body to get cold like his was. So did he pass on at 1135 pm and they didn't notice until later and that's why they didn't call until 3am? We will NEVER know but we feel he is communicating with us. My husband was very close to him. He was like a father to my husband and was always there for him. The day we put him in the nursing home his grandfather was very upset at him for doing it and they really never saw each other again. That really hurt my husband cause he loved his grandfather very very much so. We are all wondering Is this his grandfather reaching out to him to say it's ok. That he will always be with him? That he loved him and that he forgives him? I don't know but to this day it stops at that time and it's like he feels him there. Like he is there in the room with him when it happens. So for now we just leave it. But we are so curious, is this grandpa reaching out to us? My husband wonders about this everyday when he goes to look at his watch and sees that it has stopped at 1135pm.
