NAUTILUS MODEL, REF. 3710/1A-001, MOVEMENT NO. 3'231'922, CASE NO. 4'282'860, CIRCA 2006

Reference 3710⁄1, launched in 1998, is the first “Jumbo” Nautilus produced since the legendary reference 3700 which was first produced in 1976. When launched, the Nautilus model was advertised as the most expensive steel watch on the market. The main difference between reference 3700 and 3710⁄1 is the addition of the sweep centre seconds and a power reserve indicator. Reference 3710⁄1 was discontinued in 2006.
