"Sumo" earned its nickname due to its substantial size and weight, giving it a sturdy and substantial presence on the wrist.

Like other Seiko dive watches, the Sumo is designed as a dedicated diver's watch, adhering to ISO standards for water resistance. It typically offers water resistance to 200 meters (660 feet) or more, a unidirectional rotating bezel for tracking dive times, and bright luminescent markers and hands for improved visibility underwater. The Sumo is powered by Seiko's robust and accurate automatic movement, ensuring reliable timekeeping and longevity with proper maintenance. Many versions of the Seiko Sumo feature Seiko's "Diashield" hard coating, which provides scratch resistance and added durability to the watch's stainless steel case. The Seiko Sumo offers a lot of features and build quality for its price point, making it an attractive option for those seeking a high-quality dive watch without the premium price tag. Seiko has released multiple iterations of the Sumo over the years, each with slight variations in design and features. The Sumo has a strong following among watch enthusiasts and has become a sought-after model in both the new and pre-owned markets.
