The Seiko Prospex Heritage Turtle 1968 Re-Interpretation Watch SPB315J1 features a 41mm stainless steel case with a super hard coating and a silver stainless steel bracelet with a fold-over clasp. This watch is nicknamed the ‘turtle’ by Seiko fans due to its curved, comfortable shell-like silhouette. It boasts a black analogue dial with Lumibrite luminescent hands, indexes, and bezel for excellent readability in low light. A date window is conveniently located between the four and five o'clock positions, protected by scratch-resistant curved sapphire crystal glass. The timepiece is powered by Seiko's Calibre 6R35 automatic movement, offering manual winding and an impressive power reserve of approximately 70 hours. It also features a water resistance of up to 200 metres, making it suitable for diving. The dial is enhanced with gilt accents and gold-framed baton-style hour markers, all filled with luminescent material for visibility. A gold pencil-style handset also features luminescent filling. A 60-second track is incorporated for precise timekeeping. The watch is presented on an elegant 5-link stainless steel bracelet with compact clasps and a secure three-fold clasp. The movement provides an accuracy of -15/+25 seconds per day.
