Prospex Black Series Speedtimer Solar Chorongraph SSC923

Prospex Speedtimer Solar Chronograph. Designed for those who treat life as the ultimate adventure, Seiko Prospex keeps moving forward, meeting every challenge with technological excellence and winning design. This dramatic watch is part of a high-intensity collection inspired by the 1969 "Speedtimer," the world's first self-winding chronograph, extending it to the Black Series. Featuring Seiko’s "Green LumiBrite Pro," developed by combining the color most recognizable in the dark with a higher brightness and longer afterglow, this extraordinary timepiece provides a "night vision" experience for visibility in the dark resembling the view seen through a night scope. The chronograph function measures up to 60 minutes of elapsed time in 1/5-second increments and includes a split time function, while the solar cell, powered by any light source, with no battery change required, provides a 6-month power reserve when fully charged. The dark gray dial features 3 black subdials, and includes a 24-hour indicator and power reserve indicator, as well as a date calendar and green LumiBrite hands and markers. Crafted of stainless steel with black hard coating paired with a black combination nylon/ leather strap, it also includes a curved anti-reflective sapphire crystal, black tachymeter bezel, and a secure screwdown caseback. 10 bar, 100M 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
