Patek Philippe

non-tourbillon on my 3970

 

I think what makes a difference more than the tourbillon is whether the watch is automatic or manually wound.  Most Pateks with tourbillons are manually wound.  Is it the tourbillon or the fact that it's manually wound that made the difference.  I know all of my manually wound watches are incredibly accurate.  My 3970 is so accurate that twice a year when I have to set it back to/from daylight savings time, it has gained at most 5 or 6 seconds.  That's less than 1 second per month!  By the way, my 5970, which has the same movement is also very accurate, and gains about 2 seconds per week.
