Patek Philippe

I just bought nautilus 5711 g without checking the calibre at the shop. After i checked at home it is 324sc normally use in 5296 instead of 315 sc like in catalog. The no. of movement on the envelope ,original paper and in my watch are the same. Is it the... 

the literature/catelog that accompanied the watch refers to 5711/1A the stainless steel version which has a calibre 315 SC and frequency of 3Hz ,21600 semi-oscillations/hour . But the 5711G uses the 324 SC with a frequency of 4Hz, 28800 semi-oscillations/... 

Unlike most Patek Philippe movements, the caliber 324 is one of the few with a balance wheel that beats at 28,800 vibrations per hour. The high frequency contributes to accuracy, but it requires extra power. This need challenged Patek Philippe’s designers... 

to employ a different calibre on essentially the same watch ( different metals ) needs explaination and rationalisation. Calibre 324 has higher frequency 4Hz and 28,800 vibrations/hour leading to better accuracy but its movement is thicker 3.33mm compared... 

The 28800 vs 21600 woud mean a "smoother sweeping" of the seconds hand wouldn't it? I wasn't aware they had a different movement when I tried on the 5711G last week but I did think to myself it was "smoother" than the 5711/1A I had tried on a few weeks be...
