Abstract: The present invention relates to a skating device which comprises two footboard assemblies with ground contact rollers or skids; two rods, wherein each rod comprises a distal end and a proximal end. The distal ends of the rods are mounted to the footboard assemblies, respectively, and the proximal ends of the rods are mountable to a common support means located above the footboard assemblies. Each footboard assembly is allowed to move at least in two degrees of freedom with respect to the support means such that a skating movement of the two footboard assemblies with respect to the support means is possible.

Abstract: The invention relates to a watch comprising a housing (1), at least one fastening member (7) such as a bracelet, and a device for joining the housing to the fastening member. Said housing (1) is provided with a first rim (8) on the lower circumference thereof, which is inserted into a groove (13) of a support (2) that is or is not connected to the fastening member (7) in order to fix the housing to a base (14) of the support (2). A flexible element (5) and a second rim (9) can be fixed to the upper circumference of the housing (1) such that the watch is reversible. The supports (2a, 2b) of the housing are provided with an exterior part (12) for inserting rings (6a, 6b) of the bracelet (7) and a lower part (11) on which the housing (1) rests. The flexible element (5) is made of a plastic or metal thread, the ends of which are fixed in at least one guiding member (2a, 2b) that is inserted into the fastening member (7).
