Abstract: Device for fixing a watchband to a watch container includes a hinge connected to the watch container with two pivots sliding therein and a fixing element fixed to or integrated into the end of the watchband provided with two brackets defining a space therebetween for arranging the hinge. Each bracket has an axial recess protruding in the space between the brackets. The axial recess is extended in a direction of the external side faces of the brackets through an orifice containing an end stone mounted such that it is slidable in the recess and exposed to the action of a second return spring which pushes a press button fixed to the external ends of the end stone towards outside. The hinge is provided on the side faces thereof with an annular chamber having a slot which defines a privileged direction.

Abstract: The device for displaying the day of the month comprises a units display member (1) and a tens display member (2) provided one with at least one series of numerals from 0 to 9 and the other with a series of numeral from 0 to 3, these units and tens display members being positioned relative to each other so as to display in the space of a large window two numerals side by side. The units display member (1) is divided into ten sectors or a multiple of ten sectors each carrying a numeral from 0 to 9, the nine sectors (a) separating the numerals 0–1, 1–2; . . . 8–9 having an angular extent equal to ?th of the angular extent of the sectors (b) separating the numerals 9 from the numerals 0.

Abstract: The present invention refers to a constant-force device suitable for being integrated into a movement of watches, particularly wrist watches, with an indirect-second mechanism having an intermediate second pinion (14) driven by a second wheel (9) of the movement, and an indirect-second wheel (15). The constant-force device comprises a tensioning module (4, 5, 6, 7, 8), a cam (2), a lever (11), and a stop wheel (13). The stop wheel (13) of the constant-force device is mounted on the intermediate second pinion (14) of the indirect-second mechanism.

Abstract: A setting device (1) includes an outer crown body (11), an inner crown body (12) firmly connected to this, a coupling (13,14) mounted at the inner crown body, as well as a crown sleeve (15) at least partly enveloping the inner crown body (12) and the coupling (13,14), inside of which the inner crown body (12) is mounted in both axially adjustable and rotatable manner. The setting device (1) further includes an elastic element (16) exerting on at least one of the crown bodies (11,12) a force pre-tensioning it in its axial direction, the force of pretension of the elastic element (16) being determined as a function of the effective front surface (A) of the outer crown body (11), in order to allow for an automatic, axial change-over of position of the setting device as a function of the applied external pressure.

Abstract: A constant-force device for precise regulation of mechanical watch movements by means of a uniform transmission of force from the escape wheel to the regulating organ of the watch, this device being adapted to be integrated into a Tourbillon mechanism.
