What is the rate tolerance for a mechanical Carl F. Bucherer timepiece?

The watch's accuracy was absolutely remarkable, with a deviation of just 0.625 seconds per day.

The caliber named Labrador worked with a daily adjusted deviation of only 30 seconds.

Besides the manual operation, the aforedescribed time measuring method has the disadvantage that the rate of the clock reaches a relatively high value before correction begins.

More particularly, an object of this invention is to provide a fourth category of radio-clocks which presents a combination of a time measuring method for the rate of the clock with an automatic adjusting process typical for radio-clocks, the result of which is a self-contained operation.

If, according to the measurement result, the clock 49 is fast, the latter clock signal is inhibited by the correction stage 27 via the OR-gate 28 in the pulse stage (1) 29, until the measured rate is compensated.

The rate of the clock 49 is determined by the frequency stability of the oscillator 30.

At the present level of technology, excellent resonators can be produced to keep the daily rate deviations of a clock low.

With the handy Watch Expert III (Watch Matic III) watch measuring and testing device, the measured values for rate variation, amplitude and beat error are automatically calculated and displayed numerically.

The good news about this business of an irregular rate, which might otherwise cause us cast doubt on the sun’s reliability as a timekeeping reference for earthlings, is that each year brings an almost complete reset.

To be called a Chronometer, the mechanical watch mechanism must have an average course deviation of -4/+6 seconds per day.

Depending on the spring type, a thickness deviation of merely 0.001 millimetres will cause the watch to be off by about 30 minutes per day.

The most important criterion is that the watches don't exceed the maximum allowable daily deviation of minus six to plus four seconds.

The method according to claim 1, wherein the information in the installation device and/or a table comprises, in addition to a time deviation and/or running deviation, statements about the hierarchical level and/or the reception quality of multiple other already existing sensor nodes lying in the reception range of the new sensor node.

Accordingly, when observing two internal clocks of particular sensor nodes, not only may a time deviation occur, i.e., a count deviation of the particular clocks, but rather also a running deviation, i.e., a speed difference in the particular clocks.

According to a further preferred method step provided according to the present invention, at least one item of information about a running deviation between the internal clocks of the new sensor node and at least one already existing sensor node may thus be stored in a sensor node to be newly installed, particularly in a table, it being preferable here for a running speed of the particular sensor node to be ascertained from at least one measurement of the spacing of sequential synchronization telegrams of the sensor node using an internal clock of the installation device and comparison of the measured spacing to a setpoint spacing.

A conclusion may thus be drawn about the running speed of the internal clock of the sensor node and thus, if the same information is established for another sensor node, about a running deviation of the internal clocks of these two observed sensor nodes.

According to the method according to the present invention, a time deviation and/or running deviation of the internal clocks between a newly installed sensor node and at least one already existing sensor node is preferably transmitted to the sensor node to be newly installed and especially preferably also to at least one existing sensor node by the installation device or by the newly installed sensor node.

In addition to the above-mentioned information, in the method according to the present invention, the information in the installation device and/or a table may also comprise, in addition to a time deviation and/or running deviation, statements about the hierarchical level and/or the reception quality of multiple other sensor nodes lying in the reception range of the new sensor node.

This results essentially because clock information (time deviation and/or running deviation) of those sensor nodes, which lie in the reception range, is included in the information and, in addition, this information may be subjected to a further evaluation, so that only some of the possible sensor nodes are concretely used for relaying or transmitting data.
