Seiko Prospex Seigaiha-Inspired U.S. Special Edition SLA053

The dial of this U.S. Special Limited Edition carries seigaiha, the traditional Japanese pattern of overlapping ocean waves. The motif has long been associated with peace, good luck and good fortune. Seiko sets its deep blue against a black-coated case to suggest the ocean under moonlight. Only 500 were made, with each caseback engraved to identify its place in the edition.

This is a serious mechanical diver beneath the artwork. The one-piece stainless-steel case is rated to 300 meters for saturation diving under ISO standards, with a black ceramic unidirectional timing bezel, sapphire crystal, luminous hands and markers, screw-down crown and black silicone strap. Its 26-jewel automatic 8L35 movement is assembled at Seiko's Shizukuishi Watch Studio, can be wound by hand and offers approximately 50 hours of power reserve. A special collector's box completes the edition.

Our Take

We love the contrast between a wave pattern associated with good fortune and a watch engineered for demanding underwater conditions. The numbered run of 500 makes this a particularly personal way to own Seiko's seigaiha design.
