The Chameleon Arch was a piece of Time Lord technology, capable of completely transforming a Gallifreyan into another species, while retaining their genetic and physiologic essence in a fobwatch-like device, for later restoration.
This functional alloy replica watch features an etched lid and back with accurate Gallifreyan symbols, silk screened dial with gilt subdials, Breguet hands, and Hesalite acrylic crystal.
