HANDS Original

Notes

The dial of the present watch is interesting in that the hands for the time functions are in white and those for the chronograph functions are in orange as is the fifth second timing scale. Ref. ST 145.014 launched in 1969, it was the first of the ?Mark? series of watches. These watches were made to extend the ?Speedmaster? line with watches that were more ?fashionable? yet retained the qualities that had made the ?Speedmaster? the best-selling chronograph of the period.
