Seiko Prospex Alpinist SPB505
Seiko Prospex challenges every limit with timepieces engineered for superior performance on sea, sky, or land. Driven by a legacy of iconic design, Prospex continues to advance precision timekeeping for the modern world. Inspired by Seiko’s very first sports watch from 1959, this Prospex Alpinist embodies rugged elegance with a design built for high-intensity exploration.
This refined yet durable model features a classic black dial with the Alpinist’s signature Arabic numerals, wedge-shaped indices, and LumiBrite hands and markers. A rotating inner compass bezel equips the watch for outdoor adventure, while the prominently displayed Alpinist logo connects the design to its mountaineering roots.
Visible through the transparent screwdown caseback, the 24-jewel Caliber 6R55 automatic movement beats at 21,600 vibrations per hour, offering a power reserve of approximately 72 hours and manual winding capability.

What Our Clients Say About Us
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
