Today, Seiko introduces a new movement in the long-trusted 6R family that has a GMT
function and a power reserve extended to a full 72 hours. Calibre 6R54 is presented in three
new Prospex creations that are all modern re-interpretations of a Seiko classic from 1968.

The bezel inserts are made of ceramic to protect the watches from scratches.

The dial’s ice-blue colour, combined with its delicate striated texture, creates a unique depth.
Distinguished by an intricately textured ice-blue dial, this watch captures the power of the polar glaciers that shape the landscapes and seascapes of the Arctic and Antarctic, where Seiko’s reputation for reliable and durable watches was forged in the 1960s and ‘70s, when adventurers and researchers wore them on expeditions to the North and South Poles.

The additional strap compliments the dial in capturing the beauty of glacial ice.
The watch with the ice-blue dial is part of the Save the Ocean series, which is made in support of the Seiko Prospex mission to contribute to a greater understanding of the world’s oceans and their preservation.
All three watches will be available at the Seiko Boutiques and select retail stores worldwide from June 2023.
