Variant and Prototype Database

[r1chard]

Is there a site that lists variants and prototypes, at least the known ones?

Few weeks ago, I saw a 12 Flags Swatch watch with white casing.
And google showed another one with pink case and different hands.
So I ask, what else is there?

There is a very good book:

Swatch & Swatch: Modelli prototipi varianti. Milano: Electa, 1991. Catalogue for exhibition held September 12-30, 1991. 4 to. 177 pp.; illustrated.
