Rolex stopped working

[dbdedel]

Hi! I hope everybody is doing well and i wish for the success of all your tasks. I have a Rolex Submariner and Daytona. I bought this new from a Rolex dealer in the Philippines about eight years ago. I am residing in Vancouver and when i leave for about six months i put this in a safe deposit box and everytime i come back i put in a watchwinder and start using it.
Last month i got them both back and they were working fine. But this month i've noticed that the Daytona's movement was slow and then it stopped. When i used the Submariner yesterday, it stopped working. Unfortunately, there is no Rolex Service Center here in Vancouver, i may may to bring it back to the Philippines. At this point i'm curious why this happened, i have other Rolex and i never experienced this. Would anybody be able to enlighten me?
