King Seiko 56KS 5626-7200

King Seiko 5626-7200: green colour, broad facets and a cut crystal create a vivid counterpoint to the more intricate Grand Seiko 5646-7020.

The green machine

The 7200 sits well beyond the restrained end of my collection. Its colour, texture and cut crystal produce a spectacle that photographs only partly contain. When the light catches it, everything around it can seem rather low in definition.

This was not an immediate attraction for me. I initially found the design almost too eclectic. Living with it changed that reaction: the pleasure is in the force of the whole, even when it abandons the svelte elegance of quieter references.

King and Grand, in green

Beside the green 5646-7020, the distinction between King and Grand becomes especially clear to my eye. The KS green is more sprightly; its planes are broader and its folds less numerous. The GS is darker, more intricate and more ceremonious.

I read that pairing as a particularly deft expression of two different characters within the same family language. Even here, at the exuberant extremes of both ranges, the distinction feels considered.
