Unfortuately, I don't own one and can't pull a picture off the website to show you, but you need to see these cuffs for the travel-chic girl. Ok, they're a little ridiculous, but actually pretty wearable at the same time.
These stainless steel cuffs are engraved with the subway maps of a city of your choice including London, Paris, Milan, NYC, etc.
I'm going on a trip to Europe soon... perhaps I should get one for every city. Then I could put them all on at once and look like a robot! *does a poor imitation of the robot dance*
