This is a fairly large 1940’s 35.5mm. chrome plated and stainless steel
back NISUS chronograph. Look at the very interesting LARGE and flat
pushers. The movement is the fine and famous VALJOUX 23 column wheel
chronograph, just serviced and working perfectly. The dial has acquired a
fine patina over the years and retains the original blued steel pencil
hands and sweep seconds. Notice the multi-coloured red and blue outer
scales. The case displays excellent overall condition. This is a very
fine vintage chronograph which will provide many more decades of
enjoyment on your wrist.
