Signed Jaeger Le-Coultre, Joaillerie Riviere Model, Circa 1965

The present watch is foremost celebrated because of its miniature movement, which at its introduction during the Art Deco period was a marvel for the history of horology and enthusiasts alike, so much so that it broke the world record for smallest caliber. The Jaeger-LeCoultre Caliber 101 holds 98 tiny parts all held within a very compact rectangular shape and in its entirety it weighs only one gram. For lady's, its lightweight and slender appearance offers both function with a historical narrative but also it offers complete elegance with its full gold and synthetic ruby bracelet, which when worn accents the wrist unlike any other.

Jaeger-LeCoultre has long been a leader in producing beautiful watches for women that manage to combine haute horlogerie (“high watchmaking”) and haute joaillerie (“high jewelry”). It was for that reason that, for instance, that Queen Elizabeth II wore a Jaeger-LeCoultre watch with caliber 101 movement for her coronation in 1953. The caliber 101 movement has the distinction of being smallest mechanical watch movement ever made upon its introduction in 1929 to today,
