Nautilus Power Reserve 3710

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 120 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

3710/1A-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case.

An in-house automatic with central seconds, date and a power-reserve indicator, made for the Nautilus 3710 between 1998 and 2006. It marks the point at which the Nautilus moved off the Jaeger-LeCoultre ébauche the original 3700 had used and onto a Patek base. The power-reserve display is what sets the 3710 apart from the rest of the line.
