Abstract: The invention relates to a chronograph watch with a display with a first retrograde hand for indicating the tenths of a second of the chronograph and a second retrograde hand for displaying the hundredths of a second of the chronograph. The hours, minutes and seconds are displayed by corresponding hands at the center of the dial.

Abstract: Unfolding clasp (1) for a bracelet (4), comprising two lateral, articulated plates (10) with a central plate (11) so as to be able to ensure the opening of the bracelet. The plates (10, 11) are made of a flexible material able to adopt the shape of the wrist of the wearer of the bracelet. The deformation of the plates caused by a force applied perpendicular to the plane (x, z) containing the plates is greater than the deformation of the plates caused by an identical force applied in any other direction. The plates are made of a composite material, for example including a metallic reinforcement (100, 110) covered by a flexible material (101, 111) such as caoutchouc, plastic or leather.

Abstract: The watchband includes, for example, three rows of metallic links. The links of the first central row (1, 1', etc.) are shifted with respect to the links of the two other rows (2, 2', etc.). Each link of the central row (1') can pivot with respect to the preceding link (1) and with respect to the following link (1") about pins (3) connected to the links of lateral rows. Stop elements, for example other pins (4, 4') likewise connected to the links of lateral rows, allow limitation of the pivot angle of the central links about the first pins (3). The links can be removed to adjust the length of the band. Advantages: ergonomics, avoidance of the risk of pinching skin or hair, aesthetics, reduction of the wear and tear of the surface of the links, control of the curvature of the band and of the interstices between successive links.
