The term is commonly used to describe this classical case shape. This Seiko is not a Cartier, but it belongs to this dressy spirit, here in an octagonal gold-plated variant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this Seiko watch suitable for a man or a woman?\u003c\/strong\u003e\u003cbr\u003eIt is a unisex watch. Its slender octagonal case (25.5 mm wide) is equally suited to a men’s or women’s wrist, with a preference for slim to medium wrists.
