The reference that put a perpetual calendar into the Nautilus for the first time, and which Patek Philippe describes as the first grand complication in the collection. It runs the calibre 240 Q, the micro-rotor perpetual calendar movement Patek has used since the reference 3940, which is what lets the white gold case stay 8.42mm thick.
Key dates.
- Introduced as the first grand complication in the Nautilus collection
- 40mm across and 8.42mm thick, in white gold with an integrated bracelet.
- Indicates day, date, month, leap year and moonphase on a blue sunburst dial with the horizontal Nautilus embossing.
- The slim case height follows from the micro-rotor architecture rather than a full-rotor movement.
- Through the sapphire caseback the calibre 240 Q shows a gold micro-rotor recessed into the movement plate, not a full rotor sweeping across it.

How do I check a Patek Philippe 5740/1G with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
