The first Grand Seiko debuted in Tokyo in 1960. The reference 3180 was made by Suwa Seikosha. 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 "Chronometer" on their watches. In response, the Japanese Chronometer Authorization 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.

Thick tapered lugs with brushed tops and polished edges have a lug to lug length of 49mm and a thickness of 14mm giving the watch an impressive wrist presence.

As this watch predates Grand Seiko becoming its own brand in 2017 you have both at 12 o’clock an applied “Seiko” at 6 o’clock and applied “GS” with Grand Seiko Spring Drive GMT printed underneath. On the reverse, we have a screw-down exhibition case back. Inside a Spring Drive Cal. 9R66A Showcasing the CÔTES DE GENÈVE finishing. 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 generates a small electrical charge that activates an electronic circuit and quartz oscillator. Therefore there is no need for a battery. The watch comes fitted on its original Seiko 20mm polished and brushed stainless steel bracelet with a signed folding clasp and also comes with its Seiko presentation box and papers.
