Reverso One
Duetto Moon
Overview
Reverso One
The Reverso One has an elongated case, bringing a daring sense of feminine grace to the Collection. Its intricate, flowing lines, jewelled finishes and subtly decorated face create a sense of graceful sophistication. It is a watch that is inimitably, breathtakingly beautiful.
Femininity in style
The Reverso One features delicate details that bring out its femininity. Its diamond-set gadroons bring a beautiful brightness to the dial, and pair perfectly with the sunray guilloche finishes on the dial. Further enhancing its look, the refined Arabic numerals give the dial an even more graceful and feminine touch.
Heritage
Born out of a challenge
In 1930, businessman César de Trey was challenged to find a way to protect the glass of a watch for polo players during matches. de Trey’s idea was inspired; a case that could be flipped over. He approached his friend Jacques-David LeCoultre to produce the watch and the pair engaged René-Alfred Chauvot to design it. And so the Reverso watch was born.
Made in our Manufacture
From its calibre to its case, every Jaeger‑LeCoultre 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 watch 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.
