Hodinkee debuts the latest version of one of the watch world's most elegant timepieces, the Louis Cartier Tank XL Slimline. This version of the watch gets a sleeker and slimmer profile and is now officially the slimmest watch Cartier currently sells. And of course an iconic watch like this wouldn't be complete with a proper mechanical movement, inside the svelte case Cartier used nothing but the best, Piaget's ultra-thin 408 hand-wound movement.
