Overview
The sophisticated watchmaking collection
The Master Ultra Thin watch collection epitomises Jaeger-LeCoultre’s philosophy of uniting technical virtuosity with timeless aesthetics. It reimagines traditional complications with designs that feature rich, clean lines. The entire collection showcases our exceptional watchmaking savoir-faire.
Heritage
A legacy of mastering thin calibres
Already renowned for its complicated pocket-watches, the new challenge of the twentieth century led Jaeger-LeCoultre to make one of the most prodigious collections of ultra thin calibres in watchmaking history.
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.
