Expressions of beauty
Design
A modern expression of femininity
The Calibre 101 was designed to redefine women’s watches, to create timepieces that blend intricate, precision watchmaking techniques with the radiant beauty of high jewellery. Since 1929, the collection has pushed the boundaries of modern, sophisticated and truly elegant timepieces.
New aesthetic realm
The exceptionally small size of the Calibre 101, and its unique shape, gave our master craftsmen and women greater creative freedom than ever before. Unrestrained by size they could create timepieces that blended the best of high jewellery with precision time keeping.
A shimmering array of gems
Our gem-setters meticulously craft each bracelet in the collection. Using our signature Griffe setting technique in the Métiers Rares Atelier, they allow the highest quality diamonds to sparkle and shine. The sides of every case are decorated with artistic engraving, adding an artistic flair and subtle detail to every piece in the collection.
The 101 is truly remarkable. It remains the smallest mechanical calibre ever made, opening up exciting new possibilities to create exquisite, intricate high jewellery timepieces.
Created for timeless style
Our in-house artistic team takes a jewellery-led approach to create pieces of timeless style and sophistication. This approach ensures that every timepiece in the collection is a work of art, stunning in its beauty and an expression of refined elegance.
Heritage
Born from the duoplan calibre
The Duoplan Calibre served as the inspiration for the later Calibre 101. Watchmakers had endeavoured to create small, elegant timepieces for women, however traditionally smaller mechanisms meant sacrificing precision.
