The Formex Reef GMT 42mm Automatic COSC 300M Black/Red is a Swiss-made dive and travel watch engineered for precision, durability, and versatility. Designed with a robust stainless steel case and a striking black dial accented by a red GMT hand, it allows the wearer to track multiple time zones while maintaining the rugged performance of a professional dive watch. Powered by a COSC-certified automatic movement and equipped with a scratch-resistant ceramic bezel, the watch delivers exceptional accuracy and reliability. Its combination of high water resistance, refined finishing, and tool-free strap and bezel changes makes it a versatile timepiece suitable for travel, adventure, and everyday wear.

The watch features a 42 mm 316L stainless steel case with a thickness of approximately 11.4 mm, a lug-to-lug length of about 47 mm, and a lug width of 22 mm for versatile strap compatibility. It is powered by the Swiss Sellita SW330-2 self-winding movement with 25 jewels, a 56-hour power reserve, and official COSC chronometer certification for precise timekeeping. The black dial has a multi-finished surface with hand-applied elements and Super-LumiNova BGW9 on the hands and indexes for excellent visibility in low light. A scratch-resistant ceramic bezel with a 48-click mechanism allows tracking of an additional time zone. The watch includes a screw-down crown and double gasket construction for water resistance up to 300 meters, while the decorated movement and skeleton rotor are visible through the sapphire exhibition caseback.
