Overview
A reference for time
The Master Control collection is defined by true technical excellence and its celebrated round design giving it a sense of true contemporary elegance. Jaeger-LeCoultre’s spirit of innovation drives continual calibre enhancements across the Master Collection range but its soul remains effortlessly sophisticated.
Heritage
A time reference since 1992
The sleek look of The Master Control collection takes its inspiration from the classic designs of the golden age of watch making in the 1950s. The collection was launched in 1992 as a homage to the unmatched fine watchmaking heritage of Jaeger‑LeCoultre.
Made in our Manufacture
From its calibre to its case, every Jaeger‑LeCoultre luxury watch is designed, manufactured and assembled under one roof, at our Manufacture in the Vallee de Joux. Our obsession with quality is renowned as every Jaeger‑LeCoultre model undergoes strict “1,000 Hour Control” testing. This unique program provides internal certification tests that far exceed official chronometry tests.
It includes movement testing before and after casing and extends throughout assembly, according to conditions that match daily wear. A quality seal is engraved on the back of every watch once it meets our strict standards.
