This Sea-Gull women's watch pairs a 316L stainless steel case with an 18K gold bezel and a zircon-set finish, driven by the ST4200 automatic movement with 29 jewels and a 38-hour power reserve. The 25mm × 31mm round case is just 0.4 in thick and is fitted with a synthetic sapphire crystal, a black onyx crown, and a transparent caseback that shows the movement at work. A matching 316L stainless steel bracelet with a butterfly push-button clasp completes the design, and 3 bar water resistance handles everyday splashes. The watch weighs 2.4 oz and is backed by a 2-year warranty.
