Jaeger-LeCoultre Polaris Q9028471 42 mm White Dial

The Polaris Q9028471 keeps the collection's 42 mm stainless-steel case but reduces its thickness to 11.92 mm. A white sunburst dial with pushers presents a chronograph, 30-minute counter, hour counter and tachometer, with the larger case giving each indication room to remain legible. The deployant clasp and 100 metres of water resistance support the reference's practical character, while the round profile stays more contained than the thicker chronograph variants.

Calibre 751 is an in-house automatic chronograph movement with two barrels and a 65-hour power reserve. Its 25.6 mm diameter and 4 Hz frequency work with a full rotor, column wheel and vertical clutch. That architecture gives the Polaris Q9028471 a clear mechanical identity, combining automatic winding with a chronograph system shaped for precise, purposeful operation.
