1. The external influence of the flower bed clock. It is the various influences from the outside of the flower bed clock, which depends on the working environment and temperature of the flower bed clock. Commonly used measures include: shockproof design, waterproof design, antimagnetic design, additional protective shell, etc.
2. Adjust the balance wheel. The fast and slow hand of the flower bed clock is an economic structure that is convenient for time adjustment, but both theory and practice have proved that it will affect the isochronism of the system, and may also produce position differences. These timing errors are relatively random and cannot be compensated or offset. The solution is: minimize the distance between the inner and outer fast and slow needles; but the best way is to adjust the speed by adjusting the inertia of the balance wheel without the fast and slow needles.
3. The effect of friction. Friction usually has both positive and negative effects. It has a positive aspect, such as the friction between the sub-wheel, the friction between the spring and the barrel of the automatic watch, the self-locking of the screw, etc.; on the other hand, the friction will lead to the reduction of the transmission efficiency. And the wear of parts, thus affecting timing. Commonly used solutions: improve the lubrication conditions of the flower bed clock, and choose different lubricating oils according to different requirements.
