This Sea-Gull mechanical wristwatch pairs a dual time zone display with a retrograde calendar and an open heart aperture that reveals the automatic ST2573 movement inside. The 44mm round case is cut from 316L stainless steel and topped with synthetic sapphire crystal, while the lug-to-lug span of about 1.99 in shapes how it sits across the wrist. Its 31-jewel movement runs at 21,600 vibrations per hour and winds automatically, so it keeps going through normal wear. Water resistance to 5 bar covers everyday contact with splashes and rain. The strap measures about 7.48 in long and 0.87 in wide, and the watch is offered in White, White/Black, and Brown/Black.
