This Sea-Gull Business watch pairs a 40mm round 316L stainless steel case with a synthetic sapphire crystal and a leather strap, giving it a clean, formal look suited to daily office wear. The automatic ST2130 movement winds itself as you move, so there is no battery to replace, and the calendar display keeps the date visible at a glance.
With a 5 bar water resistance rating, it stands up to splashes and brief contact with water, while the 20mm strap and pin buckle keep the fit simple to adjust. The 40mm case diameter and 10.5mm thickness make it a comfortable size for most wrists, and the 48.3mm lug-to-lug span helps it sit neatly under a shirt cuff.
