Seiko Prospex Alpinist Watch SPB155

1959 Sport 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 over 60 years of sports watch excellence with recreations and reinterpretations of landmark achievements. A modern reimagining of Seiko's first sport watch, introduced in 1959, this distinctive timepiece follows a highly successful Spring 2019 limited edition and more recent additions to the line. With a smaller case to fit contemporary tastes while evoking a vintage feel, this versatile watch features a gradated green dial with date calendar and LumiBrite hands and markers, as well as a curved anti-reflective sapphire crystal. The 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 70 hours, and can be wound manually or automatically. Crafted of stainless steel, with screwdown crown, see-through caseback, and secure tri-fold push button release clasp. 20 bar, 200M 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
