Seiko Prospex Marinemaster 1968 Heritage Diver's Watch SLA079

Prospex Marinemaster 1968 Heritage Diver’s Watch. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. A streamlined and updated homage to Seiko’s landmark 1968 diver’s watch, this extraordinary timepiece is part of the high-intensity Marinemaster collection, complete with special features designed to enhance safety for intrepid divers. As a result of the skillful control of color and texture, the high contrast between the dial and indices provides improved visibility for a professional tool while the subtle pattern provides an appealing luxury feel. The uniquely textured black dial features LumiBrite coating on the hands, markers and 12 o’clock marker on the black uni-directional rotating elapsed timing bezel for superior visibility in low-light conditions. In addition, there is deeper knurling on both the bezel edge and the screwdown crown for ease of use. Further enhancing the legibility, the dual-curved sapphire crystal features anti-reflective coating on the inner surface. Following ISO standards for scuba diving to depths of up to 300 meters, this exceptional timepiece is powered by the 26-jewel 8L35 automatic mechanical movement, hand-assembled at the Shizukuishi watch studio to provide the enhanced torque necessary for a diver’s watch, along with manual winding capability, a frequency of 28,800 vibrations per hour, and a power reserve of approximately 50 hours. Crafted of stainless steel with super-hard coating, this rugged high-performance watch also includes a date calendar, secure screwdown caseback, and a tri-fold push button release clasp with secure lock and extender. 300m Water Resistant.

    I can’t say enough wonderful things about my experience, especially thanks to Sterling at Dejaun Jewelers. I had been searching everywhere for the limited-stock Seiko “Pepsi” SSK047 — it was sold out almost instantly and nearly impossible to find. This watch was a gift for a close friend who never asks for much, and this was the one thing he truly wanted. I was determined to find it for him. When I reached out, Sterling immediately reassured me that they had a few in stock. His communication was warm, clear, and incredibly patient as he confirmed everything I needed to know. He understood how meaningful this gift was, and within just a few hours of placing the order, he surprised me by sending the UPS tracking number. That level of responsiveness and care is rare these days. Sterling turned what could’ve been a stressful search into a smooth, heartwarming experience. Thanks to him, I was able to secure a special, hard-to-find watch for someone who truly deserves it. I’m deeply grateful and highly recommend this team. If you’re looking for honesty, commitment, and exceptional service, Dejaun Jewelers is the place.

    I had an amazing experience purchasing our rings here, and I want to give a special shout-out to Sterling. From the very beginning, he made the entire process smooth, stress-free, and enjoyable. He was incredibly patient, knowledgeable, and responsive to every question I had — even sending updates along the way so I always knew what was happening with the order. When the ring arrived, he shipped it immediately and followed up with tracking information right away. It’s rare to find someone who genuinely cares about customer satisfaction the way Sterling does. His professionalism and kindness made us feel taken care of throughout the whole process. If you’re looking for great quality jewelry and outstanding service, especially with someone who will go above and beyond for you, ask for Sterling. Highly recommend
