AS upgraded version of the Jaeger-LeCoultre Moon Phase Master, the new moon phase uses the integrated movement cal.925, which has greatly improved its stability through long-term improvements. The difference between the new version of the Moon Phase Master and the old version is that the moon phase disk has been replaced, and the strap has been upgraded to the latest version. Quick release, the buckle curvature is increased to improve the comfort of the wearing experience. The logo on the disk has been upgraded from printing to a metal logo, and the overall texture has been greatly improved. Everyone is welcome to play with it.
