With a two-tone stainless steel bracelet featuring a lay-flat clasp and a sleek black face, the Stiletto Tank from Citizen is a unisex watch that always looks its best. The 5.06mm ( /- .25mm) thick design showcases Citizens decades of expertise in slim timepieces, and the bold square shape is anything but ordinary. Topped off with Eco-Drive technology, meaning it is powered by light, this is one watch that every watch aficionado should own.
