Just for my purposes, I've made this list, since the clues came out.

Breguet - Euphiemia
Tag Heur - Serph
provided the clue: Cartier - Midori
in the clue: Omega - Gokudera
Breitling - Heat
Chopard - Luliu
in the clue, a wolf: Rolex - Haine
a wolf: Oris - Ikki
? Tissot - Kira
in the clue: Audemars Piguet - Axel
? Franck Muller - Shigure
Bvlgari - Shuro
a wolf: Philip Patek - Traci 13

The question marks are pepole who seem to be acting together. I'm not sure about Midori.
