Here we have a rarely seen 2018 Grand Seiko Spring Drive 'Kira Zuri' SBGA387 exclusive US Limited to 558 pieces. Inspired by the Japanese art style Kira-zuri, which translates to “sparkling painting,” this technique adds a sense of shine and vibrancy to the artwork. It features a brushed and polished 40mm stainless steel case that gently curves over your wrist, with tapered, drilled lugs. Highly polished surfaces, resulting in a lug-to-lug measurement of 46mm and a case thickness of 12.5mm, which gives the watch an impressive wrist presence. On the right side is a screw-down signed crown that sits slightly recessed. A smooth, polished bezel holds a flat sapphire crystal, AR-coated on the inside, above a stunning blue 'Kira Zuri' textured dial. An outer minute track surrounds the Zaratsu-polished baton indexes, with facet edges marking the hours. At 3 o’clock, a framed date window is located. Elegant dauphine hands are Zaratsu polished with razor edges, complemented by a blue sweeping second hand, between the 7 and 8, a power reserve. At noon, the words “GS” and “Grand Seiko” motif; at 6 o’clock, a black printed “Spring Drive” completes this striking, mesmerising dial. On the reverse is a screw-down exhibition case back with the watch's details etched around its edge, inside a Grand Seiko Cal. 9R65 Spring Drive, the innovative Spring Drive movement is mechanical but with an electromagnetic escapement regulated by a quartz oscillator. It has 30 jewels and a power reserve of an impressive 72 hours; its sole power source is a mainspring that drives a series of gears. A rotor connected to the end of these gears then generates a small electrical charge that activates an electronic circuit and quartz oscillator; therefore, there is no need for a battery. It comes paired with its original brushed and polished Grand Seiko 19mm 5-link stainless steel bracelet, secured by a signed push-button three-fold clasp. All links are provided, plus two 19mm Grand Seiko straps and a deployant buckle. This watch is sold with its original Grand Seiko box, swing tag and Grand Seiko paperwork.

The first Grand Seiko debuted in Tokyo in 1960. The ref:3180 was made by Suwa Seikosha. In 1962, Taro Tanaka developed a set of design guidelines known as the "Grammar of Design," which aimed to create a cohesive look for Seiko watches. These guidelines encompassed nine key principles that distinguished the watches. Some of these principles involve Zaratsu polishing that makes the watch surfaces shine beautifully and reflect light in interesting ways. There’s also an emphasis on using unique shapes for the watch cases, ensuring that every part is perfectly shaped, and adding features like sharp, clean edges and well-designed hands and markers that catch the eye. Today, Tanaka's principles still apply to the modern Grand Seiko philosophy. Rather than sending its 25 Jewels Chronometer movement to the Swiss to be tested, Seiko decided to do the testing themselves. The European Chronometer Official Association believed that a chronometer-rated watch had to be independently tested to be awarded that designation. Seiko watches were not independently tested, so therefore they could not be chronometers. The ECOA did what irritated watchmakers do: they wrote a stern letter to Seiko requesting that the designation of Chronometer on Grand and King Seiko watches stop. Seiko obliged and ceased using a chronometer on their watches. In response, the Japanese Chronometer Authorisation Association was started in 1968 as an independent group to test timepieces to chronometer standards. The Association was short-lived: due to the rise of quartz watches, it closed in 1983. Today, Grand Seiko movements are tested over 17 days in 6 positions compared to COSC testing over 15 days in 5 positions. In 1985, Suwa Seikosha became Seiko Epson Corporation. In 2017, Seiko announced that Grand Seiko would become an independent brand.
