A watch with an analog time display has at least one minute hand and one hour hand. This watch is moreover equipped with a fly back hand mechanism which has at least one minute fly back hand and/or hour fly back hand located coaxially to the hands of the normal time display. In the normal mode, the fly back hand or hands is/are moved synchronously with the hands of the normal time display and relative to them in an overlapping position. They can be stopped in a timer mode for marking of any instant of time and after expiry of any time interval, for again synchronously running with the hands of the normal time display. The actuated coupling of the fly back hand mechanism is located preferably non-coaxially to the axis of the motion work of the watch.
Watch, with an analog time display which has at least a minute hand and an hour hand, and with a fly back hand mechanism which has at least a minute fly back hand and/or an hour fly back hand located coaxially to the hands of the normal time display, the fly back hand or hands in a normal mode of the watch being moved synchronously with the hands of the normal time display and relative to them in an overlapping position, the fly back hand or hands being adapted to be stopped in a timer mode for marking of any instant of time and to be moved, after expiry of any time interval, for again synchronously running with the hands of the normal time display, again into the overlapping position relative to the latter.
Fly back hand mechanism for integration into a watch with hands for an analog display, which has at least one fly back hand which is arranged coaxially to the axis of the motion work of the watch, wherein the fly back hand or hands in the normal mode of the watch is/are moved synchronously with the hands of the analog display and relative to them in an overlapping position, wherein they can be stopped in a timer mode for marking of any instant and wherein they can be moved, after expiry of any time interval, for again synchronously running with the hands of the analog display, again into the overlapping position relative to them, and wherein at least one actuated coupling of the fly back hand mechanism is located non-coaxially to the axis of its fly back hand or hands.
