n 1993, the Seiko Landmaster series was born in Japan. Throughout its three-decade history, the series has earned the trust and met the needs of adventurers and mountaineers with repeated improvements to its specifications. In commemoration of the 30th anniversary of the series, Seiko presents a new Prospex creation whose design is the high reliability of successive generations of Landmasters and the design of the most representative models.

With this new Landmaster, a light and comfortable fit is ensured through a case made of pure titanium, a material with excellent corrosion resistance, while a super hard coating protects from scratches. The compass ring and rotating bezel, hallmarks of the Landmaster series, have been given a three-dimensional shape for ease of operation and legibility. Powering the new Landmaster is the in-house caliber 8L35, created to withstand harsh environments. This highly accurate movement was assembled and adjusted by the skilled craftsmen and women of Shizukuishi. On the bracelet, an adjuster function allows the user to adjust the length easily so that the watch can be worn over heavy Arctic clothing.

Three-dimensional indexes and thick hands ensure high legibility even in harsh environments. Each of the hour markers has a generous coating of Lumibrite, as do the hands. The sapphire crystal with super clear coating ensures high legibility from any angle.

The blue gradation dial represents the view from the top of the Mount Everest. It’s said that at high altitudes in the mountains, where the air is thin and there is no diffuse reflection, the sky appears dark even during the daytime. The dial’s color expresses the way the sky gradually shifts to dark blue as the climber ascends step by step, as if the universe can be glimpsed through the sky.

The case back bears the words “Limited Edition” and carries the individual watch’s serial number.
