About the Grand Seiko Sport Collection

The Grand Seiko Sport Collection represents the brand's commitment to combining rugged durability with sophisticated design. Launched to meet the demands of active lifestyles, this collection incorporates advanced technology and robust construction to ensure reliability under the most challenging conditions. The idea behind the Sport Collection is to offer timepieces that can withstand physical rigour while maintaining the precision and elegance that Grand Seiko are renowned for.


An elegant yet dynamic attitude and attention to detail define the Grand Seiko Sport watches. They come with robust cases, some characterised by smoother curves, while others have more angular construction. The use of materials, such as stainless steel, titanium, and ceramic known for their strength and lightweight properties, showcase the collection’s performance-driven attitude.

Like any Grand Seiko watch, the dials are exceptionally designed, featuring interesting textures, colours, and configurations. Also as effective sport watches, the Grand Seiko Sport models offer maximum legibility, often by incorporating Lumibrite for enhanced visibility in low-light conditions. An ergonomic construction facilitating easy operation is conspicuous on bezels, crowns, and pushers. The overall design balances sportiness with elegance, making these watches suitable for both adventurous activities and sophisticated settings.


The Grand Seiko Sport collection features a variety of sport watches, including dive watches, GMT, and chronographs. One standout timepiece is the highly-precise chronograph SBGC201, driven by the brand’s Spring Drive movement, showcasing a unique arrangement of sub-dials. Additionally, the collection includes another impressive chronograph with a more robust and sporty look, the SBGC223. The GMT watches in this collection are also noteworthy for their combination of performance and aesthetics, designed to be versatile for everyday wear.

Calibre 9R66 was released in 2006 as a GMT iteration of the popular 9R65, which is touted as the most standard 9R Spring Drive movement by Grand Seiko. It powers several GMT watches by the brand with an additional 24-hour hand and features additional functions like a power reserve indicator. It boasts 30 jewels, an automatic winding system, and approximately 72 hours of power reserve.
