Automatic watches use the movements of the wrist to re-wind the barrel spring and thus supply the necessary energy for the correct functioning of the watch. When the user cannot wear the watch it is proposed to place it on an automatic re-winding device. The device according to the invention is compact and modular. Furthermore, in order to avoid any error of manipulation, the starting and stopping of the re-winding device is done automatically by means of a detection of the presence of the watch (3). The passing of the strap in the detachable base (2) produces the tension of the device.

The grooves preferably extend across the horizontal dimension of the watchwinder to a point short of the front of the housing for concealment purposes, and are made relatively wide in relation to the dimensions of the housing to improve rigidity of an interlocked grouping of watchwinders and to simplify assembly. Preferably, the channels are of equal size and shape and spaced equidistantly apart. An array of interlocked watchwinders can be built up to varying size and shape, and one or more of the watchwinders can be selectively removed from anywhere within the array without disturbing the others.
