In 2013, Girard-Perregaux released the Constant Escapement L.M. to critical acclaim and won the ‘Aiguille D’Or’ at the GPHG (Grand Prix d’Horlogerie de Genève) in the same year. The model included a constant force escapement, a mechanism that delivered remarkable rate stability irrespective of the available energy. The Neo Constant Escapement is the latest evolution of the Maison’s groundbreaking approach to master energy, incorporating an array of aesthetic and technical advancements. Moreover, this new timepiece upholds Constant Girard’s original idea of showcasing the beauty of functional elements, but expressed in a contemporary way.

Neo Constant Escapement

The master of energy

The Neo Constant Escapement incorporates numerous examples of the Maison’s inventive spirit, manifest with the model’s 13 patents. The escapement, the mechanism that controls the flow of time, is a unique design based on the elastic and bi-stable properties of a buckling silicium blade. This component delivers a linear supply of force to the balance irrespective of the available energy within the twin barrels. By serving the regulating organ with a constant force, the rate of the watch will remain stable. Rate stability is not the same as precision, it’s arguably more important. Indeed, once the movement is regulated, a constant force mechanism will ensure the rate does not fluctuate, conferring superior chronometric performance. Moreover, the watch is a certified chronometer (COSC), providing independent assurance of its timekeeping prowess. Formed of Grade 5 titanium, the case measures 45mm in diameter at its widest point, making it smaller than its forebears. Moreover, the sides of the intricately formed case taper inwards, both towards the sapphire crystal ‘box’ as well as near the sapphire caseback. Skeletonised dauphine-style hour and minute hands, featuring rhodium treatment, articulate the prevailing time and, courtesy of luminescent material, remain visible in restricted light. The Neo Constant Escapement is fitted with a fabric effect rubber strap secured with a titanium triple folding buckle incorporating a micro adjustment system, allowing the wearer to fine-tune the strap for the optimum wrist fit.
The Calibre GP09200

The Calibre GP09200

The silicium escapement spring, with an ultra-fine buckling blade at its centre, is made in a laboratory setting using a technique called ‘photolithography’. This elaborate process has allowed Girard-Perregaux to create intricately shaped components not achievable using traditional milling or stamping techniques. In this instance, Girard-Perregaux has exploited the high elasticity of silicium, the only material that allows the blade to repeatedly buckle and, in so doing, serve the balance with a constant force. The design of the Neo Constant Escapement allows the wearer to see partial views of the motion works, a theme of disclosure that extends to the escapement spring, the balance, the escape wheels, etc. In this instance, the escape wheels are supported by two independent bridges, presented in a stealthy-shade of black, each held in position with a gleaming screw. The design of the bridges was inspired by the famous bridges of the 19th century, but now executed in a modern style. Located underneath, a separate Neo bridge spans the base of the dial and supports the balance wheel. Purists will note the symmetrical design of the dial also extends to the verso view of the movement with twin barrels at the top and two Neo Bridges at the base. A linear power reserve indicator, positioned at 9 o’clock, reveals how much energy is held within the twin barrels. The movement, the Calibre GP09200, has a linear power supply of at least 7 days.
