Seiko: From Repair Workshop to Total Manufacture
The history of Seiko begins in 1881 in Tokyo. From the creation of Seikosha in 1892 to the invention of the Astron quartz watch in 1969, the brand has always prioritized technical independence. Today, Seiko is the only manufacture in the world to produce 100% of its components, including spiral springs and lubrication oils.
The Seiko Vintage Collections in Detail
Seiko 5: The Universal Automatic
The Seiko 5 is based on five pillars: automatic movement, day-date, water resistance, crown at 4 o'clock, and robustness. It is the ideal entry point into vintage mechanical watchmaking, with calibers like the 7S26 or the 6119.
Iconic Divers: Turtle, Samurai, and Willard
- Seiko Turtle (6309): Famous for its turtle-shaped case, it is the reference vintage diver.
- Seiko "Captain Willard" (6105): Immortalized by Martin Sheen in Apocalypse Now, recognizable by its asymmetrical case (150m).
- Seiko Tuna: A professional design with an external protection "shroud" for saturation diving.
Historic Chronographs: Pogue and Bullhead
- Seiko Pogue (6139): The first automatic chronograph worn in space (Skylab, 1973) by astronaut William Pogue.
- Seiko Bullhead (6138): A radical design with pushers at 12 o'clock, equipped with a column wheel chronograph movement and vertical clutch.
King Seiko: The Zaratsu Polishing
The King Seiko (1961-1975) represented the high-end of the manufacture. It is distinguished by the **Zaratsu** polishing, a mirror polishing technique without distortion, and Hi-Beat calibers (28800A/h or 36000A/h) designed to rival Swiss chronometers.
Understanding the Seiko Dating System
Each Seiko has a 6-digit serial number allowing precise dating:
- 1st digit: The year (last digit of the decade).
- 2nd digit: The month (1-9, then O, N, D).
Example: a number starting with "82" on a 6139 indicates production in February 1978.

What is the difference between King Seiko and Grand Seiko vintage?
Grand Seiko was the absolute pinnacle of the pyramid (extreme precision), while King Seiko offered similar finishes with slightly different chronometry adjustments. Both collections used Zaratsu polishing.
