<p>The time correction means for the watch employs a pre-selection switch, for selecting the required correction function. This switch comprises two or more permanent magnets (3, 5) fixed to a carrier (8) projecting from one side of the watch case, so as to be movable relative to the latter. The watch case contains at least two pairs of switch contacts (2, 4) which are operated via the respective permanent magnets (3, 5). The carrier (8) has at least four different angular positions, corresponding to both switches being open, one or other switch being closed and both switches being closed, so as to provide the different correction functions.</p> |
