It bugs me each time I see Grande Complication for a chrono, a perpetual calendar or both... A Grande Complication is the combination of at least a minute repeater ( Grande Sonnerie preferred ), at least a Chrono ( Rattrapante, better ) AND
A Perpetual Calendar and a Tourbillon...
THAT is the definition of Grande Complication.
I never understood why Patek felt the need to call the rest grande complication...
