Jaeger-LeCoultre moon phase watch for men: a celestial tribute to the moon

An expert in complication watches, Jaeger-LeCoultre showcases its craftsmanship with its moon phase watches for men. The different phases - new moon, first quarter, full moon and last quarter - are displayed accurately elegantly thanks to a highly sophisticated mechanism.

What is a moon phase watch?

A moon phase watch is a complication watch that displays the different phases of the lunar cycle. The dial shows the progression of the moon: new moon, first quarter, full moon, last quarter, ascending, descending...

Its mechanism, composed of an ingenious assembly of gears and wheels, is often integrated into a module. This additional component is designed to be fitted to a basic movement, without the need to create a completely new one. This modular system enables watchmakers to faithfully reproduce the lunar cycle and to offer a captivating spectacle to the wearer.

Technical precision in the service of beauty

The lunar month, with its 29 days, 12 hours, 44 minutes and 2.8 seconds, demands exceptional precision. Most men’s moon phase watches round off this cycle to 29.5 days, resulting in a slight shift after a few years. Jaeger-LeCoultre’s most precise complication watches overcome this imperfection by incorporating especially sophisticated mechanisms. 

Such is the case with the Quadriptyque, capable of retaining its precision for over a thousand years, or the Master Grande Tradition Calibre 950 moon-phase watch for men, which combines a perpetual calendar and moon phases.
