It was the first Nautilus model to feature a complication, which until then had always been a time-only wristwatch. The reference 3710/1A marked the first complication from all its predecessors; it was the first-ever Nautilus to have a complication other than the date function - it was an addition of a power reserve indicator. It was exclusively produced in stainless steel until it was discontinued in 2006, the 3710/1A is fitted with a matte black dial and applied Roman numerals that are filled with luminous materials to aid reading of the time display in a darker shade. The power reserve complication, or IZR for Indication de Zone de Remontage, is displayed between 11 and 12 o’clock, a rather interesting placement adding to the charm of the present lot. With the arrival of ref. 3710/1A also marked the first time that the "Jumbo" case proportions were used in a Nautilus other than the original 3700, as part of the comeback of the “Jumbo” 42 mm case diameter prized by collectors. Produced for a sweet 8 years, it was a momentum piece that lead to future development by Patek Philippe to introduce further complications into the successful line of Nautilus.
