Standard size of box has been characteristics identified and it des not allowed to arbitrarily increase the winding length. Because of the power output, the most effective value is 55% barrel spring to occupy 60% of the space, when its power through the transmission gear, the movement power will consume in the long distance transmission. In the barrel rotation torque falls below a certain value, the friction effect, it will stop operating.
This requires winding the spring with high efficiency, long service life, and starting rotating torque can be kept to a minimum range of changes, plus storage the greatest kinetic energy in the smallest space, so the R & D personnel has been a long time fake watches committed to extend the continuous operation of the power reserve watch time. Simply say, long energy reserve, it is winding through the extended length or increasing the intensity of spring to achieve. However, due to the limited space within the movement, it can no longer increase the number of turns winding wound, and soon reached the physical limit, so it can be used in tandem within the movement over barrel structure to indirectly extend the length of winding, which makes the Omega a longer travel time.
For example, Lange, Lange 31 watch movement in the everlasting power of the two barrel up and down, and arranged together in series to achieve the effect of dynamic overlay, making the movement continued to run time doubled. The movement of the winding two barrel very long is about 1.85 m.
Although the increase lower box section in the movement, it needs more space, but also implies the need for more parts, increase the complexity and sensitivity, swinging chains separated by a small shape of the spring which will drive gossamer chain re-connected so that it can be the first day of the full string to the spring which will release the full 31 days, close to a constant speed output torque driven escapement institutions.
