King Seiko, Prospex, Presage, and Astron commemorate Seiko’s 145th anniversary.
The Seiko story began in 1881 when company founder Kintaro Hattori opened a shop in Tokyo’s Ginza district for the import, sale, and repair of timepieces. Occasionally, Kintaro had his timepieces engraved with an intricate pattern that was popular at the time, allowing his company to showcase the beauty of its craftsmanship. From its early days to the present, Seiko has always sought to provide not just a means to tell the time, but a way to enrich the lives of its customers with joy and beauty through timepieces. In 1892, Kintaro established his own factory, Seikosha, to produce his own timepieces, and in just three years created his company’s first pocket watch, the Timekeeper. Kintaro’s pioneering spirit laid the foundation for Japan’s watchmaking industry and has driven innovation and progress for the past 145 years.
Today, King Seiko, Prospex, Presage, and Astron unveil new limited-edition models whose gold-colored accents express Seiko’s enduring commitment to enriching lives with joy and beauty.
Astron
From the beginning, the Astron name has always been imbued with a spirit of innovation. In 1969, Seiko launched the Quartz Astron, the world’s first quartz watch, and subsequently opened its patent to the world to bring precise time to everyone. In 2012, the Astron name was revived when the world’s first GPS solar watch was launched.
The new GPS Solar Dual-Time Chronograph celebrates Astron’s spirit of innovation, with gold-colored accents gracing every part of the watch – from the dial and bracelet to the case. The bezel features a gold-colored sapphire crystal insert that adds depth and dimension. Even the gold-colored markings at 1, 4, and 5 on the UTC scale offer a subtle tribute to the 145th anniversary.
Powered by Caliber 5X83, the watch automatically connects up to twice a day* to the GPS network, and connects manually with the simple push of a button, to maintain its precision anywhere in the world**.
*When the dial detects sunlight, the watch connects to the GPS satellite network and adjusts automatically to the correct time. If the watch is hidden from light, it remembers the time of its last successful manual connection and attempts to receive the GPS signal again at that same time.
**If there are changes in the region / time zone / DST, manual selection may be required. Each anniversary creation is marked on its back to denote its status as a limited edition. The watches will be available from February 2026 at the Seiko Boutiques and select retail stores worldwide.
