Since the beginning of Seiko in 1881, the company has continued to innovate in line with the founder’s philosophy to be “Always one step ahead of the rest.” In 1924, the company introduced the first wristwatch with Seiko on the dial, signifying the beginning of the Seiko brand. The year 2024 marks the 100th anniversary of this landmark event. The limited edition commemorating the 100th anniversary features a silvery-white dial and is produced in a limited edition of 1,000 pieces.Ever since its first divers watch in 1965, Seiko has developed new technologies, features, and designs that have made the Seiko Prospex divers watch collection a favorite among professional and recreational divers the world over.Continuous innovation and enhancements over the decades in safety, reliability, legibility, and ease of use have made Seiko a leader in divers watches.The Marinemaster is Seikos flagship series for divers watches. Equipped with a robust and high-performance movement with stable accuracy designed exclusively for divers watches, it represents the top tier of Prospex watches in a diving category that is integral to the history and culture of Seiko.The edges of the case and bezel are mirror-finished to prevent snagging and damage to the equipment used by divers, creating a brilliant appearance while improving functionality.For the first time in a Seiko divers watch, the new Marinemaster creations feature an exhibition case back, allowing a view of the finely finished, high-performance mechanical movement. By reconsidering the case structure and using the slimline Caliber 6L37, Seiko created what is its thinnest mechanical divers watch currently (12.3mm) while adding a view of the movement.Wearability and comfort are paramount in the new Marinemaster. The entirely new bracelet features ellipse-shaped links with mirror-finished, dual-curved surfaces.
