Why this one
The case for this one.
- Perpetual calendar that reads day, date, month, leap year and moon phase without a single correction needed
- Ultra thin caliber 240 Q built around a 22 karat gold micro rotor
- Royal blue sunburst dial with white gold Arabic numerals that shifts with the light
The 5327G sets Patek's calendar complications inside a Calatrava case built for daily wear, not just the display cabinet. Day, date, month, leap year and moon phase are all read off a royal blue sunburst dial finished with the white gold Arabic numerals the Grand Complications line is known for. Under the case back sits the caliber 240 Q, an ultra thin automatic movement with a micro rotor, proof that a perpetual calendar can still sit flat against the wrist.
