Seiko’s reputation as a manufacturer of world-class diving watches began in the 1960s when the brand began equipping explorers and researchers for their Antarctic expeditions. Using the information gained from these field tests, Seiko was able to fine-tune its cases and movements to withstand some of the harshest environments on the planet. Today, Seiko’s Prospex diver’s watches remain among the most popular in the world, and the brand’s “Re-interpretation” archive models are sought after by collectors.

Among the latest additions to the Prospex range are three modern reinterpretations of legendary Seiko diver’s watches from the 1960s and 1970s with their cases left mostly original and dials updated with colors and textures inspired by polar ice. . Seiko’s commitment to polar exploration, meanwhile, has evolved into a commitment to protecting the world’s oceans, and the brand is taking advantage of the launch of this new collection to contribute to several important conservation initiatives. Here’s an overview of the watches, as well as the causes they help support.

The original Seiko diver’s watch from 1965 featured an automatic movement and 150m water resistance, both useful for scientists who wore it in Antarctica.

The deep blue dial, meanwhile, is an artistic homage to the color and texture of the polar glaciers. ($1,625)

The cause: The PADI AWARE Foundation Marine Debris Program

The world’s largest underwater citizen science movement and cleanup initiative, also known as “Dive Against Debris”, the program brings together over 70,000 divers to create the world’s most comprehensive underwater database on seabed debris. This vital information is then shared with nonprofits, governments, and communities to help them create comprehensive conservation and cleanup plans.

The cause: The National Polar Research Institute of Japan

This scientific organization conducts research in the Arctic and Antarctica and helps humanity to better understand the impacts of climate change on these sensitive regions. Seiko diver’s watches were provided to Japanese Antarctic research expeditions in the 1960s, and Seiko resurrected that tradition in 2021, donating Prospex diver’s watches to the 63rd Japanese Antarctic Research Expedition.

The cause: Fournoi underwater study and excavation project in Greece

Seiko supports this underwater archeology project aimed at exploring and preserving a historic site off the Greek island of Fournoi.
