Official description

Seiko Watch of America has announced the introduction of two extraordinary U.S. Special Editions celebrating the ancient “Seigaiha” or “blue ocean waves” pattern. Exclusively available in the U.S. market, the watches, part of the high-intensity Prospex collection, combine the finest dive watch technology with centuries of tradition and craftsmanship.

First appearing in Japanese art in the sixth century, the layered concentric circles of Seigaiha, while used in other cultures, gained particular prominence as a motif in the art, fabrics and ceramic- and lacquer-ware of Japan, with each arched wave representing surges of good luck, peace and good fortune, as well as power and resilience. The two new watches, with their Seigaiha-patterned dials in vivid blue (SLA053) or deep burgundy (SLA059), add another rich element of symbolism in evoking the role of the moon – a token of enlightenment, dreams and spirituality in both the Shinto and Zen Buddhist traditions – with the blue representing the ocean waves under moonlight and the burgundy, the first rays of sun brightening the dark seas at dawn.
