Catalogue description

Dealer description — Huntington Company

History and Significance The Grand Seiko SBGR325 belongs to the brand’s Heritage Collection, created to reflect the purity and precision of early Grand Seiko design. Introduced in 2023 as a limited production model, it draws inspiration from the original 1960s references with its compact 37mm case and balanced proportions, while incorporating the brand’s modern finishing standards and high-performance mechanical movement. The light blue sunburst dial has become a signature aesthetic of contemporary Grand Seiko, symbolizing clarity and natural light, two central themes in the brand’s Japanese design philosophy. The watch is powered by the automatic Caliber 9S65, developed and assembled in Grand Seiko’s Shizukuishi Studio, known for its accuracy and meticulous attention to finishing detail. The SBGR325 stands as a bridge between traditional mechanical watchmaking and the brand’s ongoing pursuit of functional elegance.

Silicon components, connected watches, optical-lattice research clocks and a thriving independent scene.

Smartwatches became the world's best-selling watches, while mechanical watchmaking focuses on craft, innovation (silicon components, new escapements) and independent makers.

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.
