Seiko

King Seiko is a luxury sub-line of Seiko that originated in the 1960s and is characterized by sharply angular case shapes and a high level of finishing. The collection was revived in 2022, taking on a role in the high-price segment for collectors as it was reintroduced with modern specifications while adhering to its established design language.

Seiko Prospex is a sports and professional collection officially offered by Seiko, centered on models designed for specific uses such as diving, piloting, and field activities, with features including advanced water resistance, durability, and specialized functions.

Seiko 5 Sports (Seiko 5) is a practical mechanical entry-level range that began in the 1960s, characterized by designs focused on everyday practicality, including durability, an automatic winding mechanism, and a date display.

Seiko Astron is a high-performance line centered on GPS solar technology, offering models that combine automatic time correction via satellite reception with solar charging. It is positioned as a collection that foregrounds technological appeal, with uses and customer segments distinct from the mechanically focused Presage and the adventure-oriented Prospex.

Lukia is a collection primarily aimed at female users, characterized by designs incorporating dial decorations that reflect the aesthetic sensibility of Ginza, case sizes, and jewelry-like elements. Positioned as a line intended for wear in both women’s everyday lives and formal settings, it offers a gender-specific proposition.

Seiko Presage is a dress collection centered on mechanical movements, emphasizing Japanese aesthetics and traditional craft-inspired dial expressions, such as enamel, lacquer, and delicate finishing. It differentiates itself through the finishing and details of its mechanical watches, occupying a position with a different target audience and field of expression from the sports- and technology-oriented Prospex and Astron.
