You know the feeling: you're in a foreign city with a subway, but you don't want to look like a tourist. No, you're Parisian - anyone can see that! Your style, your aura of ennui, your je-ne-sais-quoi... You wouldn't be caught dead pulling out that metro-map, screaming 'Hey, I don't actually live here!'
Designhype have come to the rescue with their metro cuffs. Can't tell your Porte des Lilas from your Porte d'Orléans? Nothing a quick glance at your wrist won't fix. Clever! They'd be even better I think if they were to execute them in a precious metal instead of stainless steel. Jewellery with a plus.
Btw, the metro seems to be inspiring others as well. Check out Tokyo Arteria here.
