Seiko’s watch names include collections under the Seiko brand and distinct brands with their own identities. Grand Seiko became independent in 2017, Credor became independent from the Seiko brand in 2019, and ALBA began as an affordable-watch brand in 1979. Because catalogs vary by market, the current U.S. list is a regional snapshot—not a worldwide inventory of every Seiko name.
This guide explains the principal brands in the title and the collections listed in Seiko’s U.S. catalog. It does not attempt to cover every historical, discontinued, or regional line.
Key takeaways
- Seiko’s official U.S. catalog labels King Seiko, Prospex, Presage, Astron, 5 Sports, Seiko power design project, Coutura, and Diamond Collection as collections.
- Grand Seiko and Credor are distinct brands, not simply Seiko collections.
- Seiko’s official history dates Grand Seiko to 1960 and its independence to 2017; Credor was born in 1974 and became independent from the Seiko brand in 2019.
- ALBA launched in 1979 as an affordable-watch brand. The research does not establish its current lineup or availability in every market.
What is the difference between a Seiko brand and a collection?
A brand has its own identity and positioning; a collection is a product family within a brand’s catalog. Seiko’s U.S. catalog calls its listed product families “Collections,” while Seiko’s official history describes Grand Seiko and Credor as independent brands. These terms should not be treated as interchangeable.
The official Seiko U.S. collections page lists King Seiko, Prospex, Presage, Astron, 5 Sports, Seiko power design project, Coutura, and Diamond Collection. This is a U.S. catalog snapshot, not proof that the same names or ranges appear in every country.

Seiko’s FAQ characterizes Grand Seiko as a luxury brand, with watches made in two exclusive watchmaking studios using exclusive movements and high-grade materials. This makes Grand Seiko more precise to describe as an independent luxury brand than as simply the most expensive Seiko collection.
