Sea-Gull Extraordinary Simple Dial Calendar 40mm
The Sea-Gull Extraordinary Series is a mechanical wristwatch built around the ST18 automatic movement with 24 jewels and a 42-hour power reserve. Its 316L stainless steel case measures about 40mm across and 9mm thick, topped with a synthetic sapphire crystal, while the leather strap closes with a push button hidden clasp.
A calendar function and 5 bar water resistance make it a practical everyday companion, and the 20mm strap fits wrists comfortably thanks to the 48mm lug-to-lug span. The watch carries a 2-year warranty.
