Seiko Prospex Speedtimer Mechanical SPB515

Prospex Speedtimer Mechanical. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world. Based on Seiko’s Speedtimer models of the past, this powerful creation offers superior timekeeping combined with sporty elegance and wearing comfort. Framed by a countdown timer dial ring that can be utilized to measure the remaining time of a particular event, the hairline-finish black dial displays the word “Speedtimer,” honoring Seiko’s legacy of sports timing. The sporty dial is accented by an orange-tipped second hand and offers a date calendar and LumiBrite hands and markers for superior visibility in low light conditions. With an upgraded power reserve of approximately 72 hours, 3 full days, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour with manual winding capability. Crafted of stainless steel with super-hard coating, this rugged yet refined watch is 200 meter water resistant while boasting the slimmest case of any Seiko 6R model, flowing seamlessly from the case to the multi-row bracelet. Topped with a curved sapphire crystal with anti-reflective coating on the inner surface, it includes a screwdown crown and caseback, and a tri-fold push button release clasp.

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
