This is an **Invicta Reserve Bolt Zeus Chronograph** watch (likely model 26801 or similar from the Zeus series). It features a bold 52mm gold-tone stainless steel case and bracelet, a textured black carbon fiber dial with three sub-dials for chronograph timing, a tachymeter bezel marked with "SZ" (Zeus signature), Swiss quartz movement, and 500-meter water resistance—ideal for a rugged, oversized sports chronograph.
