Seiko Prospex Speedtimer Solar Chronograph men's Watch SSC957
This new limited edition collaboration combines modern watchmaking with car making heritage in a stunning 1960s style design. First introduced in 1969, the ‘Speedtimer’ was a major innovation milestone in Seiko’s watchmaking heritage. Nissan Motor Corporation’s ‘Datsun,’ Japan’s leading sports car brand, launched in the same year.
In 1971, the Datsun 240Z car, also known as the Fairlady Z – adorned with Seiko logo sponsorship – won the East African Safari Rally, one of the world’s toughest races. The Datsun 240Z parallels the Seiko Speedtimer with its stylish, resilient and reliable high performance.
This Speedtimer watch features many design elements from the original DATSUN 240Z rally car: the colour scheme, the font from the instrument panels of the vehicle and the DATSUN logo on the dial. A 3-dimensional emblem of the winning car is engraved on the case back alongside the limited edition number, whilst the bi-colour aluminium bezel features a tachymeter speed measurement tool.

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
