The silhouette of the Laureato by Girard-Perregaux

Girard-Perregaux is pleased to unveil the new Laureato Absolute Light & Shade, a model that draws on the Maison’s amassed watchmaking know-how and employs its vast expertise working with innovative materials. Measuring 44 mm in diameter, the case of this latest model is made from metallised sapphire crystal, endowing the watch with a fascinating brilliance.  On one hand, the model exhibits a visually light appearance and bestows transparency, while conversely it looks dark and reflective. This visual lightness is accompanied by a low mass of just 85 grams. Throughout its composition, the watch juxtaposes contrasting characteristics, distinguishing this contemporary expression of fine watchmaking as quite unique.

 

When Girard-Perregaux released the inaugural version of the Laureato in 1975, its masterful blend of different shapes proved distinctive, yet harmonious. Its looks complemented a lounge suit but also worked with casual attire. Over the years, the Maison has introduced new complications and worked with a variety of materials and colours, but the Laureato has always remained instantly recognisable and has always retained its timeless looks.

In order to create a watch with a sapphire crystal case, a boule of sapphire crystal must be created using a technique termed ‘the Kyropoulos growth method’. This protracted growth method transforms alumina powder into a solid block of sapphire crystal, a process that takes up to 8 weeks. Thereafter, the block is cut into small discs which are then skilfully machined to form the bezel, case middle and caseback. Once this phase is completed, the parts need to be thermally treated and then polished. The components are carefully screened, only those corresponding to the specifications and without inclusion are selected. The sapphire crystal components are then subjected to a metallisation treatment. This process involves applying a surface treatment to the parts within a vacuum. Ultimately, this suffuses them with a smoked appearance. The creation of this sapphire crystal case requires 170 hours of complex work.

 

Since Constant Girard created La Esmeralda, the Maison has repeatedly fused aesthetics and functionality, creating numerous watches that showcase the company’s horological prowess and mastery of shapes. The new Laureato Absolute Light & Shade upholds this ethos by revealing the movement to glorious effect courtesy of the sapphire crystal case. The mainplate of the in-house movement, the Calibre GP01800-1143, is octagonal- shaped, a respectful nod to the Laureato’s famous bezel. The skeletonised movement reveals a plethora of parts normally hidden from view, providing a fascinating vista of curves and lines enriched with pockets of light and shade. The barrel is openworked, affording sight of the mainspring in various degrees of tension. Likewise, the balance wheel can be seen oscillating to-and-fro in a bewitching dance. The gold oscillating weight is openworked, inviting the wearer to admire the bridges below. Upholding Girard-Perregaux’s reputation for refined finishing, the NAC-treated bridges and mainplate incorporate sandblasting, traits-tirés, circular satin finishing and bevelling, with no less than 55 hand-polished inner angles.

 

Refinement is a reoccurring characteristic with the Calibre GP01800-1143. It is fitted with a variable- inertia balance. Most watches feature an index regulator which alters the effective length of the hairspring, making the watch run faster or slower. With a variable-inertia balance, the length of the hairspring is fixed and the rate is altered by adjusting the inertia weights fitted to the spokes of the balance wheel. This system delivers greater stability as well as superior shock resistance.

 

Powerful and elegant, openworked hour and minute hands ensure excellent readability. A three-dimensional ring sitting between the bezel and the movement, plays host to the GP logo at 12 o’clock and the remaining 11 indexes. Girard-Perregaux has employed a unique construction method, obviating the need for a conventional casing ring. The case and the movement are assembled on a single axis, from the caseback to the bezel, by a very specific screw system. The demanding design of these screws requires micron-level precision to hold the different components together. Two black, PVD-treated titanium lugs are integrated within the case, uniting the watch head with a black rubber strap.
