Among the Maison’s innovations were the diminutive LeCoultre Calibre 7HP, introduced in 1880 for small enameled and gem-set watches and LeCoultre Calibre 6EB, introduced in 1908, which measured barely more than 1 centimeter square.Īppearing in 1929, Calibre 101 represents the apotheosis of this quest to merge accurate timekeeping with tiny dimensions, conclusively demonstrating Jaeger-LeCoultre’s mastery of micro-mechanical engineering. However, the designs are utterly different in both form and character, emphasizing the creative freedom allowed by the diminutive Calibre 101.Īs watchmaking became increasingly sophisticated from the late 19th century onwards, Jaeger-LeCoultre developed new solutions to many horological challenges including miniaturization. Both bracelet-type watches adhere faithfully to the classical high jewelry codes and are composed of pink gold set with diamonds using only stones classified IF (Internally Flawless) to VVS (Very Very Small Inclusions).

Whereas designing a watch normally takes the opposite approach, beginning with the case and then creating bracelets or straps to complement it. First, designing the forms of the bracelets and the style of gem-setting, then integrating the cases and movements into the designs. It is also one of the world’s oldest movements that continues to be in production.įor the two new diamond-set timepieces -the 101 Snowdrop and the 101 Bangle-, Jaeger-LeCoultre’s in-house artistic team has taken a jewelry-led approach. At 14mm long, less than 5mm wide and weighing barely one gram, the tiny, hand-wound calibre remains the smallest mechanical movement in the world.

Developed half a century before the advent of computer-aided design and production technology, Calibre 101 is a remarkable feat of miniaturization. Originally conceived and developed for jewelry watches and introduced in 1929 by JLC, Calibre 101 revolutionized feminine watchmaking. These two entirely original designs reaffirm the unique alliance between high jewelry and fine watchmaking made possible by this exceptional mechanism. Jaeger-LeCoultre places its Calibre 101 in the spotlight again by releasing two new High Jewellery watches.
