Our thinking started a few years ago when we were approached by Professor Christopher Harvey of the department of neuroscience at Harvard. At that time, Prof. Harvey was studying the way our brain makes sense of information displayed on a watch dial and how it understands time. He was studying the process that transforms a graphical representation of time into an orientation in the dimension of time.
One of his findings was that the way watches with hands represent time might not be the most efficient way to indicate multidimensional information in the glimpse of an eye. According to Prof. Harvey the unique and patented Ressence dial (ROCS) corresponds to a more natural way of representing information. Ressence was onto something.
Another output of his study was that colours are the easiest and hence the fastest way for our brain to determine a moment in time. After all, it is natural light that regulates our biological clock, not a watch.
