Catalogue description

Dealer description — Analog/Shift

Seiko makes fantastic watches. Pure and simple. This piece, a Reference 6138-0011, dates to circa 1970s and features a 44mm stainless steel round case with hooded lugs, a black tachymeter bezel with red-orange accents, a matte black dial with stacked silver subsidiary registers with a matching handset, a matching and correct stainless steel 'H-link' bracelet with a signed expanding blade clasp, and last but certainly not least, Seiko's automatic-winding day-date chronograph movement within - operated by ultra-cool piston pushers. What more do you need? With a very funky period-style and excellent functionality, it's not hard to see why these 1970s Seiko chronographs are developing a cult following. This example is in great shape and captures the 70s aesthetic of the period brilliantly. These watches are a complete case study in Seiko design and we love to offer them at Analog. These are wonderful timepieces that represent just about everything that we love about vintage and are overlooked by many. Don't make that mistake!

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
