Patek Philippe

240 Caliber

 

240 caliber only windsin the CCW direction.  The 324 can do either, but the CW is what Patek Philippe uses on its winders for the 324. 

240 is very different than the 324.  Slower beat, micro rotor, and on the 240 caliber the second hand will always be at 4 o'clock position.
