Embodiment Construction

[0033] The following describes how to successfully manufacture a watch, a watch mechanism and a shaft for a watch mechanism having a relative magnetic permeability of less than 1.01, or individual parts thereof. Here, it is realized that all individual components have a relative magnetic permeability of less than 1.0100. Preferably, the relative permeability is between 0.99 and 1.01 or 1.0100. The watch is preferably a wristwatch or a pocket watch, but the watch mechanism can also be incorporated in other watches. If a non-magnetic material or component is mentioned below, this means a material or component with a relative magnetic permeability of less than 1.01, preferably less than 1.0100.

[0034] The watch mechanism has a travel time mechanism and an optional additional mechanism. figure 1 shows a cross-section of one embodiment of such a watch mechanism, while figure 2 with image 3 show figure 1 The enlarged part.

[0035] The travel time mechanism has a driving m...

Abstract

The invention relates to a mechanical clock or measuring instrument having metal parts, wherein each part of the mechanical clockwork has a relative magnetic permeability of less than 1.01.

Description

technical field [0001] The present invention relates to a watch mechanism, a watch and a measuring device without magnetic features as well as a method and an axel for the manufacture of said watch mechanism, watch and measuring device without magnetic features. Background technique [0002] There are certain situations where any magnetism is undesirable or even dangerous. For example, in the field of explosive ordnance clearance, even a weak magnetic field is sufficient to trigger the induction detonation device of a bomb or landmine. Therefore, the NATO standard STANAG 2897 for the inspection of non-magnetic tools used in the field of explosive ordnance clearance requires a total magnetic signature of at most 5 nT (nano Tesla). [0003] Electronic or mechanical watches with metal parts according to the prior art always have magnetic features. The current flow of a digital or quartz watch produces a relatively high magnetic field for these conditions and thus a strong mag...
