Patek Philippe

Reliability story

 

Dear All - I have a question about movement and reliability of my Patek Aquanaut:  As a regular reader/contributor, it can hardly escape our attention that there have been some issues with this aspect of our favourite watches.

But my story is odd, and has never happened with any other watch I have owned (Rolex, Omega etc). My 5167 is relatively new, purchased this year. For the first few months with normal wear, without any intervention, it lost approx 1.5 seconds per day. Then after approx 2 months, it suddenly lost 5-10 minutes a day. I reset the time, in order to get a more precise idea of the problem, and the issue immediately went away (it now seems to lose about 1 second per day).

This is an automatic watch and there is presumably a fault of some kind, but I noticed that when screwing in the crown following re-setting the time that there is an automatic winding process (have others noticed this?). Could it be that the watch needs re-winding occasionally?

Any comments on this would be most helpful - thanks!
