Abstract: A ribbon comprises weft threads (11) and warp threads (13) arranged respectively along the width and the length thereof and presenting in a narrow part (10) of its width at least one zone designed to be secured to a buckle, in which the weave is less close-woven than elsewhere to permit virtually continuous adjustment along its length. The weft threads are threads which are at least partially made from synthetic material and which are appreciably stiffer than the warp threads. The weft threads are joined in pairs of adjacent threads by the warp threads.

Abstract: To avoid having to pierce them, which would be detrimental to their mechanical resistance to pull, the end portions (5, 6) of the wristlet are retained in slots (3, 4) provided in the watch-case middle (1) by pins (7, 8) partly accommodated in grooves (9, 10) formed in one surface of the slots (3, 4).

Abstract: The watch comprises a plurality of stores, each containing a particular item of time data and each producing an output signal representing the data therein. A single operating button is displaceable by the user of the watch, on the one hand in the axial direction between a pushed-in position and a pulled-out position for which a switch is respectively open and closed, and on the other hand rotatably. Rotation of the button closes and opens two more switches by two cams rotationally displaced so that two pulse trains are produced with a phase relationship indicating the sense of rotation. A circuit processes these pulse trains to produce UP pulse for one sense of rotation and DOWN pulses for the other sense of rotation. These pulses are used to correct the value in a selected store. The particular store to which the correction signal is applied is selected by axially displacing the operating button from the pushed-in position to the pulled-out position a predetermined number of times.

Abstract: The apparatus comprises commutating means 10 operated by the rotation in one direction or the other of the watch spindle 1, which rotation produces trains of commutation pulses that are phase-displaced with respect to each other. The watch circuit produces from the trains of commutation pulses a signal indicating the direction of rotation of the spindle and produces selection or correction pulses. The commutating means comprise two cams 2, 3 mechanically coupled to the rotatable spindle 1, angularly displaced one with respect to the other and arranged to actuate two resiliently flexible strips 4, 5 which are fixed at one of their free ends and the other free ends of which are alternately brought into contact with and removed from respective fixed contacts 7, 8. The watch circuit can include means for rendering ineffective a predetermined number of selection pulses at the beginning of the rotation of the spindle in one direction or the other.
