Overall Impression
The watch I’m introducing this time is the Seiko Age of Discovery 30th Anniversary World Time SPL06P1.
The Age of Discovery series is a Seiko collection inspired by the Age of Exploration.
While this model offers features such as world time and an alarm, it is more than just a functional watch. What sets it apart is the way it incorporates a sense of seafaring, exploration, curiosity about the unknown, and a spirit of adventure into its design.
The world time and alarm subdials feature a world map motif, reflecting the concept behind the Age of Discovery series.

The case also features a design reminiscent of a ship’s wheel, carrying the theme through the watch as a whole.
The blue-toned hands are another detail that stands out. Combined with the world map motifs on the subdials, they give the watch an overall feel reminiscent of the sea.
The Age of Discovery series includes a variety of models, from those equipped with perpetual calendars to models with rectangular cases.
Among them, this model makes the theme of the series particularly easy to appreciate through its prominent use of world map motifs. I think part of its appeal lies in the way its functions are incorporated into the design itself, rather than simply serving a practical purpose.
I also often wear this watch when traveling abroad or flying. The world map and world time display suit the feeling of traveling, making it a watch I naturally find myself reaching for when heading out on a trip.
The caseback features an engraving commemorating the 30th anniversary of the Age of Discovery series.

Conclusion
A world map, world time, and the theme of the Age of Exploration.
I think the Age of Discovery series is about more than simply telling the time. It captures the spirit of exploration, a sense of adventure, and the appeal of discovering the world beyond the familiar.
