The upgraded version of Jaeger-LeCoultre Moon Phase Master's 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 lies in the replacement of the moon phase disk and the strap upgrade to the latest version. After removing it, the curvature of the buttons is increased to improve the comfort of the wearing experience. The logo on the disk is upgraded from printing to a metal logo, and the overall texture is greatly improved. Everyone is welcome to play with it.
