Catalogue description

Dealer description — S.Song Watches

Beginning its life as the brand set up solely to prove just how good Japanese engineering could be, Grand Seiko has successfully challenged the status quo within Swiss watchmaking to become one of the most highly regarded brands around. Ever since their 1960 founding, they have pumped out genuinely innovative creations and aesthetically astounding timepieces, both of which the SBGY003 that I have here is a testament of. While some brands gain reputations for their iconic bracelets like the Nautilus, or bezel like the Royal Oak, Grand Seiko, as a brand, has established itself as one of the best dial makers in the business, and the SBGY003 is a testament to that. Fitted with a gorgeous silver radiant sunray pattern dial, itself decorated with mirror-finish hand-polished hour markers and a razor-sharp handset, the SBGY003 is a feast for the eyes. Perfectly symmetrical with no off-center details, the SBGY003 has relegated its power reserve to the back of its movement. Upon examining the power reserve, we uncover what is perhaps the most special aspect of the SBGY003, even more so than its dial – its movement. The SBGY003 doesn’t just get a normal Grand Seiko movement, it gets one of the very best Seiko has to offer, the Spring Drive cal. 9R31. Based on the Micro Artist Studio’s 9R02, the 9R31 is a self-winding movement with 72 hours of power reserve making for a more than functional timepiece. Combining elements of mechanical and quartz watchmaking, the Spring Drive movement is famous as a hybrid solution that delivers superior performance and accuracy when compared to both conventional movement types. On top of the incredible movement and dial, the SBGY003 is a timepiece that is executed to near perfection. As demonstrated by the Zaratsu polished surfaces and beautiful satin-brushed finishing throughout, the SBGY003’s 38.5mm x 10.2mm case is a notch above the competition. With just 700 examples released, the SBGY003 makes for an excellent avenue to experience the craftsmanship Grand Seiko put into their watches, and own a timepiece that few others will own too.

Historical context

Contemporary Horology (2010 – Present)

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

Quartz, digital and electronic watches

Electronic watches arrived in three steps. The Hamilton Electric 500 (1957) was the first battery-powered wristwatch, still with a balance; Bulova's Accutron (1960) used a tuning fork. On 25 December 1969 Seiko released the Astron 35SQ, the first quartz wristwatch, closely followed by the Swiss Beta 21 group. In 1972 Hamilton's Pulsar introduced the LED digital watch, and LCD displays soon made digital watches cheap.

The 'Quartz Crisis' that followed devastated the Swiss mechanical industry, which lost two-thirds of its workforce between 1970 and 1984 before recovering with the Swatch (1983) and the luxury mechanical revival. Solar, radio-controlled, kinetic and connected smartwatches continue the electronic line.

What to look for

  • Battery hatch in the case back and calibre markings with 'Quartz' or a crystal frequency.
  • Display technology: LED (red, push-button) versus LCD (always-on).
  • Tuning-fork hum and a smoothly sweeping seconds hand on Accutrons.
  • Model and reference numbers, often printed on the back.

Dating clues

  • Electric balance watches: from 1957.
  • Tuning-fork watches: 1960–c. 1977.
  • Quartz analogue: from December 1969; LED digital: 1972–c. 1978; LCD from 1973.
