Built for extreme depths, the Sea-Gull Deep Ocean Ultra Diving Series delivers professional-grade performance with a 1000-meter water resistance and helium valve. The 45mm 316L stainless steel case houses the reliable ST2130 automatic movement, visible through a sapphire crystal. A unidirectional rotating bezel and luminous markers ensure precise timing underwater, while the integrated stainless steel bracelet with safety buckle provides a secure fit.
This mechanical wristwatch features a date calendar and a robust 28-jewel movement with a 28800 bph frequency. The blue and silver dial variant offers a striking contrast, backed by a 2-year warranty.
