Description
The SEIKO PROSPEX SBPK005 brings GMT functionality to the iconic Sumo diver platform, combining professional-grade diving capability with practical travel features. Featuring a rich blue dial and a striking blue-and-red “Pepsi” bezel, this model delivers a bold sports-watch aesthetic while maintaining the robust character that has made the Sumo series one of the most recognized collections within the PROSPEX lineup. The distinctive case shape, powerful hands, and highly legible markers ensure excellent visibility in a variety of environments.
Powered by Seiko Caliber 5K65, the watch utilizes a solar-powered GMT movement capable of displaying a second time zone via its dedicated 24-hour hand. The movement offers approximately nine months of operation on a full charge and incorporates practical functions including dual-time display, independent hour-hand adjustment, date display, overcharge prevention, and quick-start functionality. The solar charging system eliminates the need for regular battery replacement, making it especially convenient for everyday wear and travel.
Built as a true diver's watch, the SBPK005 features 200-meter diver's water resistance, a unidirectional rotating bezel, screw-lock crown, LumiBrite illumination, and a sapphire crystal with anti-reflective coating. As the first Seiko diver to combine the Sumo platform with the new solar GMT caliber, it offers a compelling blend of durability, functionality, and modern convenience.
