About this timepiece

Understated and quietly handsome, the Seiko Prospex Land automatic (ref. SPB159) brings a gray gradient dial and a black cow leather strap to a compact 38mm stainless steel case. The gradient adds subtle interest to the dial, while LumiBrite on the hands and indexes keeps it readable when the light fades. A date window adds everyday practicality without crowding the clean layout.

Seiko's caliber 6R35 automatic movement, on view through the see-through screw case back, carries approximately 70 hours of power reserve with 24 jewels and can also be wound by hand. Its curved sapphire crystal has an anti-reflective coating on the inner surface, and a screw-down crown helps deliver 20 bar of water resistance. The leather strap closes with a three-fold push-button clasp, a refined touch that suits the watch to the office and the outdoors alike.

Features

  • Gray gradient dial – a subtle shift of tone across the dial, easy to read with LumiBrite hands and indexes.
  • Caliber 6R35 automatic – 24 jewels and approximately 70 hours of power reserve, with manual winding.

  • See-through case back – shows the movement, with a screw-down crown for 20 bar water resistance.
  • Curved sapphire crystal – with an anti-reflective coating on the inner surface.

Timepiece History

Seiko's story began in 1881, when a 21-year-old entrepreneur, Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo. The first watch to carry the Seiko name followed in 1924, and Seiko went on to introduce a long line of watchmaking firsts, including the Quartz Astron, the world's first quartz wristwatch, on December 25, 1969. In 2024, Seiko celebrated the 100th anniversary of the Seiko brand.

The SPB159 is part of Prospex, Seiko's collection for sports lovers and adventure seekers in the water, in the sky and on land. Seiko's sports watch story began with the Laurel Alpinist of 1959, built for mountain climbers and field sports enthusiasts, and continued in 1965 with Japan's first diver's watch. Since then, Seiko's innovative technology has changed global standards for diver's watches.
