The iconic Patek Philippe Nautilus was first introduced in 1976 by designer Gerald Genta - however, it was not until 1998 that the first complicated Nautilus was put into production. You guessed it - the first ever complicated Nautilus is the 3710/1a “Power Reserve Jumbo”. The term “Jumbo” is coined after its relatively large, but 8mm slim, case size at 42mm. The Power Reserve allows for a 48 hour reserve, and will depict how much power it has left in the bank through its gauged scale located just under 12 o’clock.
The piece’s hour markers are distinctive roman numeral digits, creating a sense of timeless elegance. After a seven year run, Patek decided to discontinue the complicated timepiece - and has not made another power reserve gauged watch since. Unquestionably, the 3710’s value has shot up throughout the years, and will likely continue to do so. A combination of rarity, beauty, and complication equates to high desirability. Add a shortage of supply to that mixture and BOOM - this is a collector’s perfect investment grade vintage timepiece (especially one with warranty papers).
