Renowned Swiss watchmakers Jaeger-LeCoultre have recently unveiled two new models from its 101 collection the new Jaeger-LeCoultre Joaillerie 101 Reine and Joaillerie 101 Feuille watches. Stylish and beguiling these two elegant watches offer women of the world a starring role: heroines by day and by night.

Almost identical in design the pink gold Jaeger-LeCoultre Joaillerie 101 Reine and Joaillerie 101 Feuille watches have the same case, same dial and same bracelet, each are adorned with pavé diamonds 101 for the Reine, and 167 pavé diamonds for the Feuille. On the silvered opaline dial, two discreet Baton hands reflect eternal femininity. And could anything better enhance the union of mechanical perfection and jewellery excellence than pink gold? Sensuous, exquisitely feminine, and timeless, this precious metal is perfectly suited to its new starring role

The one difference between the two watches is the lid on the Joaillerie 101 Feuille model. Echoing the delicacy of a leaf, it is decorated with 57 brilliant-cut and baguette-cut diamonds. The lid itself takes the shape of a headdress and can be raised or closed at will, revealing or concealing the passage of time. Under the curves of its natural lines, the dial is either hidden from the eyes or revealed to the light of day. With this interesting feature, Jaeger-LeCoultre makes the new Joaillerie 101 Feuille more mysterious, more secretive.


Since 1929, the Jaeger-LeCoultre Calibre 101 has stood out in terms of the mastery of absolute miniaturisation. At the time, pocket watches were giving way to wristwatches, which were particularly prized by women who dreamed of wearing a jewel on their wrist that brought together the precision of mechanical operations and a refined aesthetic. This calibre took its inspiration from the famous Duoplan movement, characterised by its division into two horizontal planes, one on top of the other.

Now almost one hundred years old, and having benefited from all those years of expertise, it remains the smallest mechanical movement in the world. Contained in a volume of 0.2 cm3 and measuring 14 mm x 4.8 mm, with a thickness of 3.4 mm, each Jaeger-LeCoultre Calibre 101 is unique. Each of its components is custom manufactured and adjusted.

Weighing barely a gramme, this micromechanical masterpiece contains 98 components assembled by hand by only a handful of watchmakers, since there are only a rare few who have mastered the painstaking assembly of something so small and precise. As a reminder, its balance wheel oscillates at a frequency of 21,600 vibrations per hour, a remarkable technical challenge in terms of precision.
