This Mechanical Watch Has a “Butterfly” Inside: The Girard-Perregaux Neo Constant Escapement

What happens when you replace a traditional coiled balance spring with a 14-micron-wide silicon blade? Girard-Perregaux set out to answer that question with the Neo Constant Escapement. In this video, we go hands-on with the Girard-Perregaux Neo Constant Escapement (ref. 93510-52-3552-5CX), housed in a 45mm pink gold case. At its heart is the watchmaker’s innovative Constant Escapement, featuring a flexible silicon blade that stores energy and delivers a controlled impulse to the balance wheel. The result is one of the most visually fascinating escapements in modern watchmaking. Beneath the open-worked dial, the purple silicon “butterfly” flexes and pulses as it regulates the movement. But this isn't just about looks. Girard-Perregaux designed the system to address fluctuations in power delivery and maintain more consistent precision as the mainspring unwinds. We take a closer look at how the Neo Constant Escapement works, its impressive architecture, and what it’s like to wear this remarkable 45mm timepiece.
