Osmior Régulateur à Tourbillon Squelette

Unique edition of seven pieces      

There is a connection between the scientific activities of the company and its extraordinary presentations at the universal exhibitions: the Eiffel Tower. This icon of inventiveness, ingenuity and technical expertise in France at the end of the 19th century is still one of the most beautiful technical achievements of the modern era.   

As the ultimate mark of respect and a discreet nod to its own history, the brand has created a unique series of seven pieces, «Les Grandes Heures Scientifiques» (the Great Days of Science). Individually numbered, they present an automatic tourbillon movement entirely «skeletonised» by hand.   

A speciality of the Maison, this exclusive series of seven pieces joins the traditional MARINE and OSMIOR collections to evoke the glorious period of French Fine watchmaking led by the company from 1785.   

Each piece of the movement has been open-worked with a small hand saw then filed and bevelled. Probably only a handful of craftsmen in the world possess the secret of doing such delicate manual work.   

The hand-cutting of the pieces takes the «skeletoniser» about two months. When the time required for assembling, finishing and regulating them in the L.Leroy workshops is included, each watch finally comes to life after some three and a half months of work.   

This is another striking similarity to the Eiffel Tower which took two years, two months and five days to complete : exactly the same length of time spent by the company’s master watchmakers to produce its seven exceptional pieces.   

The L.LEROY Osmior line   

The name OSMIOR refers to an old metal alloy composed principally of gold. Its grey colour with blue reflections is similar to platinum. This precious material was regularly used by the L.Leroy company to manufacture the cases of its highly complicated watches so it was the natural name to choose for its traditional line. With its connections to watchmaking, this neoclassical name perfectly expresses the elegance and delicacy of L.Leroy watches. The OSMIOR line includes such exceptional models as the single push-button, automatic, column-wheel Chronograph, the automatic Retrograde Perpetual Calendar and the automatic Tourbillon Regulator.
