Rolex running fast

[Frakis]

Hi all,
I checked the accuracy of my watch the last few days, and found the following:

After the first 13 hours it was running +1. After 24 hours it was +3. After 48 hours it was +13. How can it jump up so much from 1 day to the next? I've read that it depends how active you are, and if you set your crown up or down will either speed up or slow down the watch. However, after 48 hours I was anticipating something around +6, not +13. Any other explanations?

First you cannot check any watch for accuracy the way you are doing it.First give your watch a full manual wind thats 40 full crown turns clockwise only.Then set your watch with a reliable time source for this test any quartz watch/clock will do thats accurate enough.Wear your watch for 8 hours plus a day with reasonalbe wrist activity to wind it and keep power reserve at peak, check time once only every 24 hours with same setting source, write down the lose or gain do this for 7 complete days.Then average out the lose or gain over those 7 days for a accurate result and your watch is not magnetised before some jump in on forum and say it is..It watch is then showing poor accuracy over the COSC spec get it regulated although some new watches need a bit of time to adapt to the owners wearing habits.

If he can turn the crown it's not magnetised.
