====== Grand Seiko (1960) ======

{{wst>author|[[Foskett, Stephen|Stephen Foskett]] ([[https://grail-watch.com/|Grail Watch]])}}

The first-generation **[[Grand Seiko]]** was produced by [[Suwa Seikosha]] for [[Seiko]] from [[1960]] until [[1964]]. It was replaced by the [[Grand Seiko 57GS]] in 1964.

Introduced in 1960, Grand Seiko model 3180 was the first [[chronometer]]-grade watch produced in Asia. It was certified internally rather than by a body like [[COSC]], but to standards even more stringent than the Swiss organization's. It was a tour-de-force design, with carved lettering on the dial, applied markers, and 18 karat gold plated cases. A few cases in platinum were also produced.

The Grand Seiko case back includes a lion logo signifying the chronometer rating. This lion logo would continue to be used until 1966, when the Grand Seiko logo superseded it.

The Grand Seiko contained a 25 jewel movement oscillating at 18,000 A/h. It was an uncomplicated movement with hours, minutes, and central seconds, but included a [[hacking]] feature, not found on other Seikos for decades.

===== Tributes =====
Seiko reproduced this design in [[2012]] for their 130th Anniversary Grand Seiko models, SBGW039/40.
