Vintage Seiko Ladies 23 Jewels Hi-Beat Automatic with Emerald Green Gradient Dial from October 1973

Seiko vintage mechanical watch
MADE IN JAPAN

“Seiko” (精工) is a Japanese word meaning “precision,” “exquisite workmanship,” or “refined craftsmanship.”
It comes from the characters:

• 精 (sei) – fine, precise, refined

• 工 (ko) – craft, workmanship

Originally, Seiko’s watchmaking division was called Seikosha (精工舎), meaning “House of Precision.”
The name first appeared on a watch dial in 1924, shortened from Seikosha and keeping the core meaning; the company itself was renamed Hattori Seiko in 1983 and Seiko Corporation in 1990.

So the brand name literally ties directly to the idea of precision engineering—which is exactly what the company wanted to be known for in its watches.

🕰️ Seiko’s 24xx automatics: a hi-beat movement in a ladies’ case

Caliber 2411A is a compact automatic built by the Daini Seikosha factory in Kameido, Tokyo, for Seiko’s women’s watches of the early 1970s. It carries 23 jewels, winds by hand as well as automatically, and runs at 28,800 vibrations per hour — a genuine hi-beat, the rate Seiko reserved for its high-grade movements, fitted into a case a fraction of the usual size.

The 24xx automatics are documented in Seiko’s Chariot line, a short-lived early-1970s dress range sold on the Japanese domestic market. Nothing on this watch names a line: the dial carries only the Seiko logo, Automatic and the jewel count, so it is described here by its reference and caliber rather than by a model name.

Seiko built these in quantity and they turn up regularly. What makes them worth having is the dial work — saturated vignette colours and brushed vertical banding that most makers of the day reserved for far more expensive watches.

Description

A Seiko 2411-0060 ladies’ automatic from October 1973, in stainless steel on its original Seiko mesh bracelet. The dial is an emerald green vignette — dark at the rim, bright through the centre — with vertical brushed banding that shows in some light and vanishes in others. Gold-tone block indices mark the quarters, plain gold batons the hours between them, and the hands are polished steel.

This is a small watch, sized for a woman’s wrist, with the bracelet integrated into the case rather than fitted to conventional lugs. Behind the case back is the 23-jewel caliber 2411A, a Daini Seikosha automatic that also winds by hand and beats at 28,800 vibrations per hour.

Seiko Group Corporation (セイコーグループ株式会社, Seikō Gurūpu kabushiki gaisha), commonly known as Seiko, is a Japanese maker of watches, clocks, electronic devices, and semiconductors. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced the world’s first commercial quartz wristwatch in 1969.

Seiko is widely known for its wristwatches. Seiko is one of the few watch companies that is fully vertically integrated. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko’s mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts internally.

Seiko offers one of the widest ranges of watch technologies in the world—quartz, kinetic, solar, mechanical, and Spring Drive—spanning everything from affordable everyday pieces to six-figure haute horlogerie. Over the decades it has launched multiple global brands, including Lorus, Pulsar, and Alba, while elevating its prestige through innovations like Spring Drive, which helped push Seiko into higher-end territory. In 2017, Grand Seiko was spun off into its own standalone luxury brand, while Credor remains part of Seiko’s own lineup, sold primarily in Japan. Seiko’s own global lineup now includes Grand Seiko, King Seiko, Prospex, Astron, Presage, and Seiko 5 Sports.

Among Seiko’s key lines, Seiko 5 (born in 1963) is the gateway mechanical series known for durability and value; Lord Matic defined 1970s style with faceted crystals and colorful dials; Astron remains Seiko’s flagship GPS-solar tech line; Presage focuses on traditional mechanical craftsmanship with enamel and urushi dials; and Prospex delivers professional-grade dive, field, and pilot watches often embraced by enthusiasts. At the top end, Grand Seiko emphasizes precision, Zaratsu polished design, and movements like Spring Drive, while King Seiko—revived in the 2020s—brings back sharp, elegant 1960s styling with modern calibres.

Finally, Credor represents Seiko’s pinnacle of artisanal watchmaking, producing low-volume pieces in precious metals and showcasing Japanese decorative arts and haute complications from the Micro Artist Studio. Beyond watches, Seiko has also produced various electronic devices and, historically, jewelry and eyewear—though those divisions have since shifted to other companies.
