This Sea-Gull automatic watch pairs a mother-of-pearl dial with a calendar and luminous hands, set in a round 34mm 316L stainless steel case with a synthetic sapphire crystal. The ST18 automatic movement, with 24 jewels and a frequency of 28,800, winds itself as you move, so the watch keeps running without daily winding.
The matching 316L stainless steel bracelet closes with a push-button hidden clasp and measures about 7.1 inches long and 0.4 inches wide, while the case stands roughly 0.4 inches thick with a lug-to-lug of about 1.6 inches. Water resistance to 5 bar covers everyday splashes, and the watch is backed by a 2-year warranty.
