The new Master Ultra Thin Moon boasts a sunray dial in a deep, intense, slightly smoky blue. With a design that is as complex as it is meticulous, this gradient midnight blue echoes the deep blue alligator leather strap. This chromatic statement divinely contrasts the pink gold polished case with profiled lugs, the applied indexes, the Dauphine hands and the minute track. A window at 6 o'clock displays the moon phase — an emblematic complication of the Master Ultra Thin collection — which finds its home amidst the bewitching background of blue shades. The aesthetic balance is remarkable. Entirely created, decorated and assembled within the Manufacture, the self-winding Jaeger-LeCoultre Calibre 925 promises 70 hours of power reserve.
