Grand Seiko releases a lot of watches. If you?re a cynic, this might be what you?d identify as the brand?s defining characteristic. They?ve developed a reputation for endless variants, swapping dial colors, textures, case shapes, and movements in every conceivable combination. There?s a joke about weather in New England, that if you don?t like it, all you have to do is wait, and you could make a similar one about Grand Seiko: if you?re after a particular dial/color/case combo that doesn?t exist yet, there?s a decent chance it?ll materialize eventually. 
But for all the SKUs in the Grand Seiko catalog, and the genuine variety you?ll find there, something was missing: a mechanical chronograph. There?s long been a line of Spring Drive chronographs (and Spring Drive chronographs with a GMT complication) but, kind of surprisingly, there?s never been a purely mechanical chrono under the Grand Seiko banner.
