Seiko Presage Cocktail Time GMT “145th Anniversary” Limited Edition Purple HCB006J JDM (40.5 mm, Caliber 4R34 Dual Time, Steel Bracelet)

Description and Key Features

The Seiko Presage Cocktail Time HCB006J is a commemorative JDM (Japanese Domestic Market) Limited Edition piece produced in Japan to celebrate the 145th anniversary of Seiko’s founding. It stands out for its exclusive textured purple dial, whose faceted radial pattern—characteristic of the Cocktail Time collection—refracts light to simulate the relief of traditional cut cocktail glass.

On the technical side, it is equipped with the Seiko Caliber 4R34, an in-house automatic movement that incorporates the second time zone (GMT / Dual Time) complication via a fourth, independently adjustable central 24-hour hand. Its solid stainless steel case (40.5 mm in diameter and 12.8 mm thick) is paired with a solid-link stainless steel bracelet, a curved, box-shaped Hardlex crystal that reinforces its classic mid-century silhouette, and a screw-down case back with a transparent display window.
