The Jaz Derby Swissonic is a so called Drivers Watch, because you don’t have to take the hand from the wheel, to see the time. It seems to be the only watch with the ETA 9176 movement. The construction is very unusual, the balance runs vertically, opposite is the battery, also vertical. It has a clear digital display with jump hour, so you always have a clear display. Signed front:”Jaz, Derby, Swissonic, Swiss”, backn:” Derby S. A., Electronic, Base Metal Bezel, Stainless Steel Back, Reg. Des. Pat. Pend., Swiss Made”, inside:” Swiss, Unadjusted, seven 7 Jewels, 9176, ETA”. The same movement is used in this Derby Swissonic desk clock.
