Prospex Alpinist SPB243

1959 Sports Watch Reinterpretation. The first Seiko sport watch - elegant, yet rugged and superbly functional - the Laurel Alpinist is reimagined in this distinctive watch, designed to celebrate the beginnings of Seiko's rise to the forefront of high-intensity timekeeping. Styled to fit contemporary tastes while evoking a vintage feel, this exceptional watch is as smooth and refined as the prized original, but far more powerful. With the original's mountain-shaped markers at 12, 6 and 9 ensuring legibility while referring to its mountaineering inspiration, this versatile design features a gray dial with date calendar and LumiBrite hands and markers, as well as a curved sapphire crystal with anti-reflective coating on the inner surface. 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 and see-through caseback, and 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
