High-tech materials
A complex attire
Ceramic
This lightweight material comprises zirconium oxide and metallic oxides. The zirconium oxide selected by Girard-Perregaux is composed of an extremely fine powder, made of micro-beads, each measuring mere fractions of a micron in diameter (1 micron (µ) = 0.01mm). By using this specific grade of micro-bead, the structure of the bracelet and case exhibit a notably homogenous appearance. This latter attribute allows the craftspeople at Girard-Perregaux to finish the ceramic components with a combination of polished and satin finished surfaces, an endearing characteristic common to all Laureato models.
The ceramic components are particularly hard, up to seven times harder than steel, delivering incredible scratch resistance, a quality that will ensure the watch retains its showroom-fresh appearance for years to come. Another attribute of the ceramic components is that they will never age or fade with the passage of time. Furthermore, ceramic is unaffected by changes in ambient temperature, it’s light, hypoallergenic and proves remarkably smooth, all factors that deliver extraordinary wearer comfort.
Many advantages
Silicon
Silicon’s benefits are multiple: it is neither susceptible to corrosion nor affected by changing temperature, is lightweight and impervious to magnetic fields. In addition, silicon’s low friction coefficient mitigates both wear and energy consumption. In 2013, we created an ingenious silicon blade for our award-winning Constant Escapement L.M. The action of the silicon blade flexing backward and forward delivered a uniform supply of energy to the escapement, thus enhancing precision. More recently, we launched the Free Bridge in 2020, capitalising on silicon’s ability to be formed into intricate shapes, using this state-of-the-art material to create not only the escapement but also a large variable inertia balance. The benefit of this approach is that the balance is more stable and less vulnerable to shock. Its aerial design as well as its large diameter further augment precision.
Hardness
Sapphire
Rated 9 out of 10 on Mohs scale of mineral hardness, sapphire is extremely hard to craft. At nearly 3,000 degrees Kelvin, fundamental particles merge under the effect of an incandescent flow of oxygen and dihydrogen. A raw block of sapphire crystal emerges from this process, which is then cut, machined, drilled, domed and polished using tools made from the hardest material in the universe: diamond. Sapphire’s crystalline transparency make it the perfect material to craft a case that would reveal all the intricacies of our mechanics, like on the Quasar and Laureato Absolute Light models. Did you know that 200 hours of painstaking work are required in order to machine and polish the case of a Quasar Tourbillon with Three Bridges?
Worldwide first
Carbon Glass
A worldwide first upon its introduction at SIHH 2019, Carbon Glass is a mix of carbon fibre and fiberglass compressed at high temperatures. Lightweight, 100 times more ductile than, the material has the added benefit of being 100% water-resistant. The raw aspect of its surface provides it with an audacious look, making it the perfect ally for our Laureato Absolute collection. In addition, the possibility to colour the fiberglass allowed for an assortment of grey, black or blue models, namely the Laureato Absolute Rock, Laureato Absolute Crystal Rock, Laureato Absolute Wired.
