. Jaeger-LeCoultre’s ‘Polaris Mariner Date’ 42mm pays homage to the brand’s original diving watch with a more technical reboot and ISO 6425 rating. Resistant up to 300 metres, this reference has been manufactured in Switzerland from stainless steel and powered by an in-house calibre 899AB automatic movement. Safety features include an orange security ring that’s only visible when the crown is not screwed in, reminding the diver to adjust their rehaut, and Super-LumiNova® coating for visibility, the seconds hand has contrast tipping to avoid confusion. The blue lacquered dial, meanwhile, echoes the depths of the ocean floor. We offer an eight-year warranty for all working parts and manufacturing faults for Jaeger-LeCoultre watches.
