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 citizen’s 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.
