Fig. 1 shows the plate first stamped and Figs. 2 and 3 show the relative positions after the connecting pieces b<1> - - b<4> have been bent twice at right angles. Parts c<1>, c' are for the attachment of the dial, the parts i<1> - - i<3> serve to support arbors of the movement and lugs g<1>, g<2> limit the expansion of the main and alarm springs.
