This Sea-Gull mechanical wristwatch pairs a 40mm round 316L stainless steel case with a synthetic sapphire crystal and a leather strap, secured by a pin buckle. The Roman numeral dial includes a calendar function, and the ST2130 automatic movement with 28 jewels and a 28,800 frequency keeps it running without manual winding.

With a case thickness of about 0.4 inches and a lug-to-lug of about 1.9 inches, it sits neatly on the wrist, while the 5 bar water resistance handles everyday splashes. The strap measures about 7.5 inches long and 0.8 inches wide, and the watch weighs 2.1 oz.
