The Grand Hagane is the artisinal or “Grand” tier sequel to the Akane, utilizing the same 37mm polished steel case and distinct handset. The roiri urushi lacquer dial, however, this time features a dusk amber hue with a "Tamahagane" pattern instead of the “hamon” pattern found on the Akane. The Hagane also utilizes Koji characters instead of numerals for the hours.
