The Seiko Landmaster Sagarmatha (reference SBCW021) was launched in November 1998. Sagarmatha is the Nepali name for Mount Everest, the highest mountain in the world. The retail price of this watch was 180,000 yen.

Introduced in 1993, the Landmaster series offers heavy-duty wristwatches equipped with functions that are useful for full-fledged mountaineers aiming to climb the world’s highest peaks such as Everest. The Seiko Landmaster Sagarmatha released in 1998 was one of the equipment of the 98 Noguchi Sagarmatha Climbing Team.

The Seiko Landmaster Sagarmatha watch was developed in collaboration with Japanese mountaineer Ken Noguchi, who became the youngest person to climb the world’s seven highest mountains, including Mount Everest. This timepiece features a 24-hour scale rotating bezel corresponding to the 24-hour hand makes it easy to calculate the elapsed time over 12 hours.

The watch case and band are made of bright titanium, which is lighter, harder, and more scratch-resistant than stainless steel. The bezel is made of ultra-hard high-tech ceramics.

The Landmaster Sagarmatha SBCW021 watch houses the Seiko 5M45 kinetic caliber. The hands and the hour scale on the dial employ Lumibrite, a phosphorescent material that allows time reading at night or in dark places. The length of bright titanium bracelet can be easily adjusted using a diver adjuster clasp so that it can be worn over a sweater or shirt.
