Seiko Prospex - 300M Tuna

PROSPEX

1975 Saturation Diver's Watch Reinterpretation. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with recreations and reinterpretations of landmark achievements. Honoring the first watch designed to withstand the dangerous world of the professional diving, Seiko's 1975 saturation diver, this extraordinary reinterpretation retains the solid can-like lines and functionality of the original, improved with upgraded specifications and materials. Following ISO standards for diving to depths of up to 300 meters, this powerful saturation diver features a durable stainless steel case and black one-way rotating elapsed timing bezel, both with super-hard coating, as well as a screwdown crown and caseback. The arrow shaped minute hands, simple geometric indices, narrower bezel markers and LumiBrite enhancement offer sharper legibility, while the anti-reflective sapphire crystal provides maximum visibility. With secure silicone strap and day/date calendar, this updated design is powered by a unique extended-life quartz battery with increased torque, engineered specifically for diver's watches. 300m Water Resistant.
