Vintage Seiko Sportsmatic Deluxe with Sunburst Silver Dial from October 1966

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.

🕰️The Era of Practical Luxury: The Sportsmatic Deluxe

Introduced by Seiko in the mid-1960s as an elevated tier of their highly successful automatic line, the Sportsmatic Deluxe brought a distinct touch of luxury to dependable daily timekeeping. Positioned above the entry-level models, the Deluxe series got better case finishing and 23-jewel movements. The Seiko 5 had already arrived in 1963 as the Sportsmatic 5, so the Deluxe ran alongside it rather than ahead of it — the dressier, date-only alternative, built at Daini Seikosha in Tokyo.

(*)Note: Stock bracelets are often shortened by previous owners and may not fit you(see bracelet size in the product images). We match the strap to this watch’s lug width, so there is nothing for you to measure — just pick a padded leather strap for Seiko from the options at the top of the page.

Why Collectors and Enthusiasts Covet This Watch Today

• The Date-Only 7605A: The Sportsmatic 5 carried a day-date; the Deluxe used the date-only 7605A instead, which leaves the dial cleaner and more symmetrical. Seiko built the Sportsmatic range in quantity between roughly 1962 and 1968, so these turn up regularly — the appeal is the configuration, not scarcity.
• Mid-Century Dial Work: A radial sunburst silver dial, applied faceted block indices, and a magnifier formed in the crystal over the date — the upper end of what Daini Seikosha was putting into a mid-1960s automatic.
• The Dolphin Caseback: Through the 1960s Seiko stamped a leaping dolphin on the backs of its water-resistant automatics, and a seahorse on the water-resistant hand-winders. The dolphin here sits alongside the reference, the serial and the “WATER PROOF / SS” markings.
• The Crown at 4 O’Clock: Seiko dropped the crown low on the case across its 1960s automatics, keeping it clear of the wrist. On the 7605A it is a setting crown rather than a winding one — the movement takes its power from the rotor alone — and it stands proud of the case flank on its own tube.

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.
