Another very 1970s watch 8110A today – the all stainless steel 67-9151. This is one of the rarer models, again having had a shorter production run than other more familiar ones. It’s eight sided case, with four of them curved, gives it a distinctive and pretty well unique look. The main dial colour is green, shaded lighter in the centre, with (as seen on the 67-9178) hexagonal sub-dials. The main hands are white with lumed centres and black ‘tails’, with white sub-register hands and an orange second hand (one variant has a yellow second hand – more info below). One side of each sub-dial on my example is shaded orange. Mine is on its original solid link bracelet, and is from January 1975:

There were three dial designs for this model, one of which also had a yellow second hand – this scan provides all the info needed to check authenticity:
