This is primarily the element that drives the pocket watch. It consists of a flat spring-steel band that is stressed in coupling or bending. It works in such a way that whenever the watch or other spring-driven part is wound, the curvature of the spring is increased and energy is stored. [pdf]

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 1. Mechanical energy storage harnesses motion or gravity to store electricity. For example, a flywheel is a rotating mechanical device that is used to store rotational energy that can be called up instantaneously. [pdf]

The Jaeger-LeCoultre 925 movement is the current calibre powering the JLC Master Ultra Thin Moon. This completely in-house JLC 925 movement stands out from the crowd because it. .
4 hands are displayed for the JLC 925 movement. We have the central hour, minute, second, and date hand which are all highly polished and very legible. The two complications other. .
One aspect that is different about the Jaeger-LeCoultre 925 movement is that it has a unidirectional rotor. That means that the self-winding rotor of the 925 calibre only winds the watch in 1 direction instead of 2. For more information. .
The icon Jaeger-LeCoultre Master Ultra Thin Moon is housed with the in-house 925 calibre. This design element is what JLC is most known. [pdf]
