Seiko's Prospex turtle watch, nicknamed the 'Turtle' by fans for its shell-like case, is a favorite among diving enthusiasts. This 44mm stainless steel timepiece features a ceramic bezel, anti-reflective sapphire crystal, and a black dial with Lumibrite markers for exceptional readability in all conditions. It is powered by the Caliber 4R36 automatic movement with manual winding and includes a comfortable, durable black silicone strap. Engineered for adventure, it boasts 200-meter water resistance, a uni-directional rotating bezel for precise diving, and an accordion-style strap invented by Seiko in 1975 to accommodate wrist expansion at depth. Since launching Japan's first dive watch in 1965, Seiko's innovations have set global dive watch standards.
