Seagull TY2806

Sea-Gull caliber TY2806 is an automatic movement manufactured in China. It features a Magic Lever winding system with a bidirectional rotor and Incabloc shock protection. The movement shares its design architecture with the Tianjin caliber ST1612, both produced by the same parent company. It appeared in the Android Divemaster Espionage and certain Hager Commando models. Notably, the movement bears no engravings or inscriptions—not even a jewel count—on the rotor or mainplate.
