Jaeger-LeCoultre Polaris Q9028181 42 mm Blue Dial

The Polaris Q9028181 gives its stainless-steel case a 42 mm diameter and 13.39 mm thickness, with a blue sunburst dial arranged around a chronograph, 30-minute counter, chronograph seconds and tachometer. Pushers and a deployant clasp reinforce the purposeful layout, while the large round case is rated to 100 metres. The reference's proportions and blue surface give the Polaris collection a clear sporting expression without adding functions beyond the chronograph display.

Calibre 761 is an in-house automatic chronograph movement with two barrels and a 65-hour power reserve. It measures 25.6 mm across and 5.76 mm high, contains 248 parts and 35 jewels, and operates at 4 Hz through a full rotor. A column wheel controls the chronograph, while the openworked JL rotor, blued screws and Cotes de Geneve on the mainplate are visible through the display back. Bevelled edges complete the movement's finish.
