When decorated components are sent to the assembly workshop to undergo a host of painstakingly detailed techniques, they offer but a mere hint of the glory of the perfectly operating movement that their union will create.

Traditional Assembling

A number of ancient techniques, often confined to the annals of history, are kept resolutely alive at audemars piguet’s traditional assembly workshop, and are performed by hand on the extrathin instantaneous date calibre 2121 on a daily basis: pinning up the spring to the collet, pinning up to the stud on the balance cock, and fitting the balancespring.


Crafting a mechanical movement is a complex art that requires perfect strokes at every stage in the process. Yet before the hundreds of components are fitted to the mainplate, the master-watchmakers must carry out a crucial pre-assembly procedure known as jewelling, which is vital in ensuring that the calibre runs smoothly.

Casing Up

Casing-up is the final stage in completing the timepiece, and is the culmination of weeks and even months of painstaking work. The movement and case must travel on a somewhat epic journey from the Manufacture’s workbench until they arrive in this workshop, and a further series of procedures lasting a month on average awaits them here.

Decoration techniques add that final touch to every piece crafted in this workshop, turning extraordinary timepieces into truly exceptional works of art.



It all starts with an idea: a new ground-breaking shape, a play on perspective and dimensions, the perfect harmony of lines and curves that the designer sketches out.
