Seiko 8T63-03N0 Doctor Yellow × Sumikko Gurashi Collaboration Limited Edition (506 of 5,000)

This rare Seiko chronograph edition was created through a special collaboration with Sumikko Gurashi and the legendary Japanese Shinkansen bullet train, Doctor Yellow – a symbol of precision, technology, and childlike nostalgia all at once. The watch was produced exclusively for the Japanese market and is limited to 5,000 pieces .

The yellow dial with the iconic figures by Sumikko Gurashi is reminiscent of the characteristic lacquer finish of the Doctor Yellow and conveys playful joie de vivre, combined with Seiko's technical reliability.

Background: Sumikko Gurashi & Shinkansen Doctor Yellow
Sumikko Gurashi (すみっコぐらし) is one of the most popular character series from the Japanese studio San-X. The name literally means "life in the corner"—the characters symbolize shy, introverted individuals who feel most comfortable sitting unobtrusively on the sidelines. Each character has its own story and personality—from the timid cat "Neko" to the leftover grain of rice "Tonkatsu." This charming world, full of gentleness and melancholy, has achieved cult status in Japan and symbolizes the need for tranquility in a hectic society.

The Shinkansen Doctor Yellow is the legendary test and measurement vehicle of Japan's high-speed trains. With its bright yellow paintwork, it serves to monitor the tracks, overhead lines, and signaling systems of the Shinkansen network. It is rarely seen, as its journeys are irregular and unannounced – and this is precisely what makes it an icon. In Japan, the passing of the Doctor Yellow is considered a lucky sign .

This watch thus combines two strong Japanese symbols: the radiant hope and precision of Doctor Yellow with the sensitive, humorous world of Sumikko Gurashi.
