PLANT LOCATION & LAYOUT

Bienne is the very heart of Rolex. It was, of course, up until 2004 a completely separate company owned by the Borel family of the Aegler company. It's hard to believe, but true. Now, there isn't a location that is more Rolex than Bienne, and going inside here is easily the most exclusive invitation in all of watchmaking. The contents of this 92,000 square meter facility are, in the world of watchmaking, essentially priceless. This is the building

inside which everyone dreams of seeing at the foot of the Jura Mountains.

The reason that Rolex allows so few people into the Bienne location is because they have created a truly unique manufacturing system where they have built machines that build machines that create unique components exclusive to Rolex. Rolex blanks of brass, copper, and steel are cut using proprietary machines unseen anywhere else in Switzerland, via spark erosion. Baseplates are produced at a rate of about 100 per minute. There are stripping machines where raw metal is inserted in one end, and out the other end comes full components with pins already in them.There are machines in Bienne that are capable of doing the work of 100 traditional tools in a matter of 50 seconds. These, dear readers, were not photographed, and I am sure you understand why. It is also in Bienne that several components unseen elsewhere in watchmaking are produced. This includes the Parachrom Hairspring and Paraflex Shock Absorber – two things that, in the opinion of many, are at the core of Rolex's superiority.

Rolex rigorously selects the materials for its watches. Each bridge of the movement, each wheel, each pinion, each element of the case, bracelet or dial is made of a material

Stainless Steel 904L stainless steel is commonly used in high-technology and in the aerospace and chemical industries. Its excellent anti-corrosion properties are comparable to those of precious metals. Rolex masters in-house the entire manufacturing process for its 904L steel watch components.

GOLD Gold Rolex watches possess a truly captivating radiance, born of years of experience in perfecting the use of this most precious of metals. Only by controlling the whole process can Rolex guarantee a peerless, enchanting lustre on its watchcases and bracelets alike.Rolex exclusively uses 18 ct gold, a princely alloy composed of 750‰ (thousandths) of pure gold, plus exactly the right mixture of elements including silver and copper necessary to produce the different types of 18 ct gold: yellow, white and Everose, Rolex's exclusive pink gold alloy. Jealously-guarded formulas ensure exceptional durability, polishability – and an extraordinary sheen that lasts for generations.

PRECIOUS STONES Through their unique brilliance and the extreme care taken in their setting, the high-quality precious stones selected by Rolex endow gem-set watches with unparalleled prestige.

CERACHROM Rolex developed and patented the Cerachrom bezel for specific Professional models to ensure lasting beauty and functionality even after exposure to the most extreme conditions. Fashioned from extremely hard ceramic material, it is virtually impervious to scratches, and its colour is unaffected by ultraviolet rays of the sun.
