Abstract
The invention pertains to the field of high frequency watch movements. The invention relates to a timepiece including a movement that has a resonator of the type with a balance and balance spring and an escape system of the type with a wheel and Swiss lever. According to the invention, the balance oscillates at more than 36,000 vibrations per hour and the escape system is at least partially pierced to decrease the inertia thereof.
