Jaeger-LeCoultre Polaris Mariner Date

The Jaeger-LeCoultre Polaris Mariner Date offers the classic diving-watch functions of hours and minutes, with a running time indicator (seconds hand) and unidirectional inner bezel, and the addition of an instantly-jumping date display. The dual-crown configuration is typical of super compressor-type diving watch cases, with the upper crown for operating the inner bezel and the lower one for setting the time and date.

Since Jaeger-LeCoultre introduced the Calibre 899, its engineers have constantly updated it to incorporate the latest performance-enhancing technology. The new-generation version powering the Jaeger-LeCoultre Polaris Mariner Date is fitted with some technical improvements to guarantee a power reserve of 70 hours.
