So, I've been going through the booklet, and apparently the symbols don't technically ALL match-up with the songs, i.e. 12 O'Clock is "Caravan", 1 O'Clock is "BU2B"...it works up til "The Anarchist" because "i The Pedlar 1" uses the symbol at 3 O'Clock, while "The Anarchist" uses the symbol at 4 O'Clock.
The clock rights itself with "Seven Cities Of Gold", which uses a symbol (Gold) not seen on the clock, a circle with a dot in it, while "Halo Effect" uses the symbol at 6 O'Clock, the symbol for Sun. After that, the symbols work their way uninterrupted. Here's the complete list:
Caravan Copper
BU2B Sulphur/Brimstone
Clockwork Angels Annealing
i - The Pedlar 1 Mercury
The Anarchist Winter
Carnies Zinc
Halo Effect Sun
Seven Cities Of Gold Gold
The Wreckers Aquarius
Headlong Flight Oil Essence
ii - The Pedlar 2 Mercury
BU2B2 Neptune
Wish Them Well Gold
The Garden Water
