Catalogue description
Dealer description — Analog/Shift
Grand Seiko is the darling of contemporary watch collectors today, and taking even a cursory glance at the design specs -- or better yet -- an example in the metal, its easy to see why. What many collectors are learning is that Grand Seiko dates back to right around 1960, and some of their earliest models featured what went on to become the hallmark design staples that are clear and present in their popular collections today. This particular example, a Reference 4520-8000, dates to the late 1960s and features a distinctive faceted-cushion case, satin white dial, 'GS' signed crown, and caseback medallion that are all parts of Grand Seiko's design language today. Coupled with its correct and matching brink-link bracelet with a signed clasp (which we prefer to any of their contemporary bracelets, we might add), we are left with a truly special and elusive package. This piece demonstrates perfectly what's so great about Japanese craftsmanship; attention to detail and refinement. Spectacular!
Historical context

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide
Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
