Why do they arouse such enthusiasm? Intimately linked with the origins of watchmaking, mechanical, manual winding watches form part of the DNA of the Jaeger-LeCoultre Manufacture. Long before the first watches, clocks were hand-wound using a key. Inseparable from the first pocket watch movement, manual winding allows the watch wearer to become a watchmaker themselves, and with it a master of passing time... Authentic, instinctive, the gesture of rewinding their watch becomes a form of ritual, both technical and poetic, which enchants connoisseurs of beautiful watchmaking. Ideal for adapting your watch in an intimate and personal way, manual winding has benefited from the invention of automatic movements, which enhances their everyday ease of use. At the Grande Maison, manual winding mechanical watches represent the quintessence of the art of watchmaking. Appreciated by women and men alike, they are embodied in many models of the Reverso Classic line, and feature alongside the finest complications such as the exceptional Master Grande Tradition Gyrotourbillon Westminster Perpetual timepiece. Transcending time and often synonymous with great finesse, manual winding remains an essential at Jaeger-LeCoultre. Among the finest manual movements developed and manufactured at the Grande Maison reigns the illustrious caliber 101 of the women’s Joaillerie 101 watch. First created in 1929, to this day it remains the smallest manual movement in the world.
