OK: take all the numbers which are placed in the glyphs at noon and at six. You get the following sequence (ordered)

3 10 13 14 15 24 33 37 38 47 50 75 83 113

All these numbers (but one) are linked together as follows

113 = 38 + 75
083 = 33 + 50
075 = 37 + 38
050 = 03 + 47 = 13 + 37
047 = 10 + 37 = 14 + 33
038 = 14 + 24
037 = 13 + 24
024 = 10 + 14

Thus, every number is 'connected' to the other ones, but the number 15. Unfortunately, 15 is the 'rotation' we had to apply to LCCTGLW to obtain ARRIVAL... but anyway.
