Seiko Prospex introduces two limited-edition diver’s watch models on May 14, 2026, with blue bezel accents, ahead of their global release at boutiques and select retailers in June 2026.

One model, the Seiko Prospex 1965 Heritage Diver’s Watch Limited Edition HBC005, is powered by Caliber 6R55 and has a 72-hour power reserve. It has a 40.0 mm stainless steel case and bracelet with super-hard coating, 300 meters of water resistance, and a recommended retail price in Europe of 1,500 euros. Seiko said the edition is limited to 4,000 pieces.

The second model, Seiko Prospex Limited Edition HBB001, is powered by Caliber 4R35 and has a 41-hour power reserve. It has a 41.7 mm stainless steel case and bracelet, 200 meters of water resistance, and a recommended retail price in Europe of 650 euros. Seiko said the edition is limited to 9,999 pieces.

Seiko said both watches use blue as a design accent tied to “Seiko Blue.” The HBC005 pairs a silver-white dial with a blue aluminium bezel insert and blue seconds hand, while the HBB001 uses a two-tone aluminium bezel insert with a silver-tone 0-to-15-minute scale and blue for the remainder.

The company said the HBC005 is based on its original 1965 diver’s watch and includes a bracelet clasp with a 15 mm adjustment range in six 2.5 mm increments. The HBB001 is described as having a sharply defined case and bracelet design.
