Jaeger-LeCoultre Polaris Q906868J 42 mm Blue Dial

The Polaris Q906868J uses the same 42 mm stainless-steel diver's case and 13.92 mm thickness as its green-dial counterpart, but changes the surface to blue sunburst. Super-LumiNova, a rotating bezel, rotating rehaut and screw-down crown support the date, hours, minutes and seconds display. The deployant clasp and 200 metres of water resistance complete the purposeful specification, giving the round case a clear tool-oriented identity within the Polaris collection.

Automatic Calibre 899 is made in-house and provides a 70-hour reserve from one barrel. Its 218 parts include 32 jewels, while the 4 Hz oscillator works with a silicon escapement. The movement is finished to a fine grade and shown through the display back. Its functions are the date, hours, minutes and seconds, and the cased watch undergoes Jaeger-LeCoultre's 1000 Hours Control.
