Prospex Speedtimer Mechanical Chronograph Limited Edition SRQ045

Prospex Speedtimer Mechanical Chronograph Limited Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Celebrating Seiko's first precision chronographs, developed for international sporting competitions in 1964, as well as its 1969 introduction of the world's first automatic chronograph, this distinctive watch,available only in a limited production run of 600 with the serial number engraved on each caseback, provides chronograph measurement of up to 30 minutes of elapsed time in 1/8-second increments. Visible through the screwdown, see-through caseback, the 34-jewel automatic movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. Framed by a tachymeter ring, the matte black dial reduces light reflection while heightening the visibility of the red indices and chronograph minute counter accents. The proprietary 8R46 movement includes a column wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand while providing longer wear and efficiency, and improving maintenance of the power reserve during chronograph operation. Crafted of stainless steel with black hard coating, specially designed pushers and crown for ease of use, tri-fold push button release clasp, and dual curved sapphire crystal with anti-reflective coating on the inner surface. The black calf leather strap features covered stitches on the inside to protect against wear from perspiration during vigorous athletic activity. Packaged in a Limited Edition collectors' box. 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
