This is a **Citizen Stiletto Eco-Drive** (likely model **AR3073-06P** or similar from the Stiletto series). It features an ultra-thin 38mm two-tone (gold and silver) stainless steel case with a matching multi-link bracelet, a minimalist champagne dial with gold baton indices, sapphire crystal, solar-powered Eco-Drive quartz movement (never needs a battery), and 30-meter water resistance—perfect for a sleek, elegant dress watch.
