Patek Philippe

hi, I have seen the change in caliber that patek has done recently, i am interested in knowing the advantage and disadvantage of each caliber. I understand that tha caliber 315 has been in thr pp 5146 sinse 1996. Has there been any difference in the 315 i... 

As it beats at 28,800 hertz compared with the 315 that beats at 21,600.

Theoretically yes, a faster beat does imply higher accuracy. However, a stable balance wheel at a slow beat can realize higher accuracy than a similar watch with a faster beat. Last but not least, the 324 has a shorter power reserve.

Agreed. However, if all else is equal, a higher beat rate will be desired. Otherwise, you will only need a higher beat rate when you have a chronograph complication.

Firsty: the wear and stress for the oszilating system is less. Secondly and more importantly: from high end manufacturers I expect accuracy also at lower beat rates. Same applies to movements: thin ones, please. Regards Moritz

I have to say that the faster beat rate does make the second hand glide a lot smoother thou
