In every aspect of the design, authentic functionality was the absolute priority. But paradoxically, with this purity of purpose come true refinement and beauty. Look for example, at the uniquely designed Arabic hour markers. The 2,4,8 and 10 numerals are silver while the 1,5,7 and 11 are in pure white. This is done to ensure that the hands contrast sharply with the dial and markers. But this subtle function-driven feature also adds depth and modern style to the whole watch. Similarly, the chronograph buttons are designed, like those on the 1964 stopwatches, to be easy to use, but they also add to the power of the overall design.
