In 1945, Valjoux's answer to the split-seconds function in Venus movements was the Valjoux 55 VBR. Note that the "V" in VBR stands for Valjoux, and the "R" stands for Rattrapante. The basic Valjoux 55 VBR is a monopusher, with the center pusher controlling the start/stop of the chronograph and the pusher at 2 o'clock controlling the split-seconds functionality – essentially the reverse of the Venus calibers. The clamp for the center wheel is also designed slightly differently, with the column wheel being entirely visible (unlike the Venus movements). These movements were also significantly larger than their Venus counterparts, measuring at about 39 mm as compared to about 31 mm for the Venus. As a result, most of the watches cased with these movements measure upwards of 40 mm.
