Interesting. First time I see something like that about a dial and its numerals

Cool!
It’s nearly the same for 11 when you reverse the angle, but it falls apart at 12 
From Carl Friedfich Gauss with love :-)
The fact that the sum of "opposite" numbers in a uniform sequence of numbers always is the same has become famous in a legend about the young Carl Friedrich Gauss who used this property to very quickly calöculate the total sum of the elements in such a sequence.
The story is told nicely here: Young Gauss and the sum of the first n positive integers

Nice :-) So then with just a little more fun math, how many "Crazy hour" watches could Franck Muller make so that the six sums as in the picture are again all equal to 13?
(Note that if the six sums give the same number, then clearly this number needs to be 13)
Answer for the nonmathematicians: 6! \times 2^6=46,080.
We should perhaps suggest Franck Muller to do this limited edition of 46,080 (unique) pieces

If you go straight across..........
11 to 1, 10 to 2, 9 to 3, 8 to 4 and so on the sum is 12.
