The chronometric instrument mounts were mainly produced by Smiths England for pre-war era automobiles and motorcycles. The measuring mechanisms are similar to a mechanical movement, hence the term Chronometric.
About various translation parts, a restlessness and locking springs, the pointer axis is "raised" by the rotation of the drive shaft. A jerky pointer movement is the first distinguishing feature of these devices and completely normal.
If the speed decreases, the pointer returns accordingly.

The advantage of these measuring devices is that they do not have any parts for transmitting the indicated speed or speed, which weaken over time (eg magnets or springs). As a result, the displays are accurate over a long period and do not change due to aging of components, but at most by resin or wear defects. In addition, a high power is transmitted and thus a slave pointer can be driven to indicate the maximum speed or maximum speed. For this reason, the measuring units (Smiths) have also been used by other manufacturers (eg VDO) for racing instruments, such as tachometers. This design is sensitive to water ingress (rust) and the complicated structure is urgently advised against its own repair attempts. The devices have a long life if they are expertly maintained from time to time.

Repairs to the Chronometric mills are made using original or remanufactured parts in original equipment manufacturer quality. Since the sometimes very complicated parts are reproduced in small quantities or in custom-made, the prices for a repair can vary greatly.

Cost estimates are always free. If extensive installation work is necessary to prepare a cost estimate, it will be calculated after consultation with our hourly rate.
