🚄 A tribute to one of Japan’s most iconic railway legends, the Seiko x Class 923 "Doctor Yellow" T4 Retirement Memorial Limited Edition Chronograph captures the spirit of a train revered not just for its diagnostic prowess—but for the luck and excitement it brings to those lucky enough to glimpse it. As a non-passenger service train with a confidential schedule, spotting “Doctor Yellow” has long been considered a rare and fortunate event among Japanese rail enthusiasts.
This exclusive quartz chronograph commemorates the final journey of the T4 unit, which traveled from Tokyo to Hakata on January 29, 2025, marking the end of an era in Shinkansen history. Subtle design cues inspired by the sleek Class 923 silhouette blend seamlessly with Seiko’s renowned craftsmanship, resulting in a timepiece that’s both nostalgic and technically refined.
Enhancing its commemorative value, each watch comes in special luxury-style packaging and includes a memorial metal card detailing the T4’s legacy—a thoughtful keepsake for collectors and fans alike.
Whether you're drawn to the elegance of Seiko or the charm of Japanese rail culture, this limited-edition chronograph is a celebration of innovation, luck, and timeless engineering—available to PRE-Order at Watchoutz.com.
