How is the quality of the LZ CollectJaeger-LeCoultre Master series fully automatic mechanical belt watch?
Appearance:In 1992, Swiss high-end wall clock brand Jaeger-LeCoultre launched the Master Control watch, which combines classic aesthetic design and excellent technology to demonstrate the outstanding watchmaking standards of the Grand Workshop. It is also a symbol of Jaeger-LeCoultre’s sophisticated watchmaking craftsmanship that has been inherited to this day. The Jaeger-LeCoultre Master series watches follow the classic design and decorate the dial with a retro-charming blue color. They can be worn casually or for business activities. The brand uses a new way to display the three iconic functions of the series: date, timekeeping, and world time, and they are all equipped with brown crocodile leather straps, showing the elegance of men. The chronograph dial logo and outer tachymeter scale are presented in bright blue Arabic numerals, and the 3 o'clock position is the 30-minute chronograph dial. The blue steel baton hours in the center and the minute hands are designed with a hollow design, which contrast with the black hour markers to clearly show the time indicated. The dense back cover can effectively ensure the safety inside the watch. In addition to the Jaeger-LeCoultre LOGO, the stainless steel back cover is also engraved with the "MASTER CONTROL" series of English logos.

Craftsmanship:The watch uses a 40mm stainless steel case, with the front surface polished and the sides brushed and polished to show the overall texture of the watch.
