Enjoy the world of major an minor -
- without any sharps and flats

This new „world“ is very easy to realize:
we just have to call the 12 chromatic tones
of an octave
12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11,
(as designed on the outer ring of
the watch face in black and white numbers),
instead of
C, *, D, *, E, F, *, G, *, A, * and B,
(as designed on the inner ring in yellow letters)

Please notice, that the 5 tones, which are marked
with an asterisk (*), do not have names for their
own; they can only be defined as, e.g.:

being „the tone above C“, i.e. C#, or
being „the tone below D“, i.e. Db.

This is not only a minor detail; this is the reason
for having our rather complicated system of
signatures, for major and minor scales, today.
This could give us the idea to try something
very easy: to give them own names:
1, 3, 6, 8 and 10.
