1 year old Rolex running slow few hours per day???

[Cuong_syd]

Hi,

I bought a brand new rolex day date ii a year ago. Its my first watch as i never wear a watch before. I bought it in Berlin, Germany and wear it daily. I took it out every night before sleep. Recently it running late about few hours in the morning. I wind it and it was able to run probably for a day or two. This morning it was slow about 6 hours again. It sucks so bad since the watch is only a year old.

On rolex website, I found a nearest rolex service centrel in Ho Chi Minh city, VietNam as im living in Hanoi Vietnam but could not find their telephone number which is strange. My question is:

1. What seems wrong with my watch? Do i need to pay to fix it or it can be done under warranty?
2. Should i trust a rolex service in Vietnam or should i send it somewhere else? I have trust issues with vietnamese services.
3. To do such service in vietnam, will it be recorded on paper and laser engraved in my watch as i read somewhere? Will it decrease the resale value of my watch?

Thank you.
Cuong.
