King Seiko Automatic Green Dial SPB391J1

This watch is inspired by the heritage of Tokyo’s past – the retro looks and pop culture during the heyday of the 1960s when the original King Seiko was released.

King Seiko timepieces contributed to Seiko Watch Corporation’s developments in world-leading technical precision after their first launch in 1961. The ‘King Seiko’ originated when multiple Seiko teams of experts created different watches to encourage innovation – one of the Japanese watch brand’s constant aims.

To give its vintage looks, the dial features vertical hairline finishing and metallic texture with a retro-luxe halo effect colouring counterbalanced by its recognisable classic KSK sharp case design. Lumibrite on the hands and indices give strong legibility. Powered by the in-house 6R55 calibre, it has a three-day power reserve.

The special feature of this model is its easily interchangeable bracelet for a personalised look – the bracelet can easily be removed by squeezing the two levers at the back of the bracelet end-piece.
Long live the new King Seiko: modernised elite watchmaking, yet its stately, dignified and majestically classic looks remain.
