Seiko Prospex LX U.S. Special Edition SNR055

Prospex LX GMT U.S. Special Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. This extraordinary Special Edition is inspired by the view of the sun setting behind earth marking where the planet ends, and space begins. The gray-blue dial has a pressed pattern reminiscent of the topography of earth, while the dual-tone dark blue and gray sapphire bezel reflects the fading blue tones as the sun disappears. This spectacular dial features a power reserve indicator, date calendar, LumiBrite hands and markers, and a gold GMT hand that echoes the golden halo effect from sun during this spectacular phenomenon. Providing exceptional precision, the Spring Drive GMT movement, with its Tri-synchro regulator, combines a 30-jewel automatic movement with the quartz regulator for an astounding accuracy of +/- 1 second per day, +/- 15 seconds per month. Offering a power reserve of approximately 72 hours, with manual winding capability, the movement is equipped with a GMT function that allows tracking of a second time zone at a glance. Crafted of light and durable titanium with a super-hard coating, this finely finished watch features a sapphire crystal with super-clear coating, as well as a screwdown caseback and crown, and a tri-fold push button release clasp. 100M Water Resistant.

    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
