Gérald Genta's Nautilus, launched in 1976 with a case shaped after a ship's porthole and its hinges. At 42mm it was enormous for the era, hence 'Jumbo', and Patek's advertising leaned into the audacity of a steel sports watch priced like a gold dress watch.
Key dates.
- Launched as Patek's first steel luxury sports watch
- The case is built in two pieces with side 'ears', not a conventional caseback — a construction that made it water resistant without a screw-down back.

How do I check a Patek Philippe 3700/1A 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.
