Are you a fan of Seiko or Japan Bullet train railways? If so, you're in for a treat! Seiko has once again partnered with an iconic JR railway line to create a special limited edition timepiece. This time, Seiko has collaborated with Sumikkogurashi, the beloved anime characters from "Sumikko Gurashi," to bring you the stunning Dr. Yellow watch.

This collaboration is a dream come true for fans of both the popular character "Sumikko Gurashi" and the legendary "923 Type Doctor Yellow" train, which ensures the operation and safety of Shinkansen trains. The watch features Sumikko Gurashi playfully peeking out from the dial, adding an element of excitement to its design.


Seiko has developed this timepiece as a special chronograph model, featuring a Tachymeter. Limited to only 5000 pieces worldwide, the Dr. Yellow watch showcases a vibrant yellow dial that perfectly matches the color of the Class 923 JR line bullet train.


At the 11 o'clock index, you'll find a shining motif of small gears, reminiscent of the "corners" found on Shinkansen wheels. The subdial at 6 o'clock represents a "forward monitoring camera" that transmits data to the central command when an abnormal value is detected.

Like other Seiko Chronograph Tachimeter models, this watch includes a stopwatch minute hand, stopwatch second hand, a 24-hour indicator, and a date display window located at the four o'clock position. 


One of the most charming features of this watch is the special 24-hour sub-dial display at 3 o'clock, which showcases Sumikko and his friends riding on Dr. Yellow. Sumikko Gurashi characters find calmness when they can find a corner all by themselves in crowded situations. If you resonate with this feeling or are simply curious about the concept of finding solace in a corner, why not become one of Sumikko's fans?

The dots, hour, and minute hands of the watch resemble Dr. Yellow's headlights and are made with Lumibrite, a special phosphorescent paint that enhances visibility. The curved hardlex windshield is designed to mimic the shape of a Shinkansen's windshield, adding a touch of authenticity to the timepiece.

The package includes a special depot station designed to resemble the home of Sumikko. Enclosed in a unique wooden box, the special packaging is reminiscent of Dr. Yellow waiting for service at the train depot.

For those who may not be familiar with Dr. Yellow, it is also known as the Happy Yellow Shinkansen Class 923. This train, officially named the Shinkansen Electric Track Comprehensive Test Vehicle, inspects tracks and overhead wires for abnormalities while traveling at a maximum speed of 270 kilometers per hour. Spotting Dr. Yellow is said to bring happiness, as it is not publicly announced when it will be in operation. It’s like having a surprise when seeing Dr. Yellow.
