This Grand Seiko Sports watch has been created with high specifications to be robust and reliable enough for sportswear, but ideal for every day.
Combining form and function: highly resistant to shock and perfected for active wear with a 200m water resistance.
Featuring a ceramic bezel, it is powered by the highly accurate 9F86 quartz movement in which every single quartz crystal has been grown in-house and tested over three months. Only the best performing crystals are selected for a Grand Seiko.
Grand Seiko: beautifully, precise Japanese watchmaking, from the pinnacle of Seiko Watch Corporation’s in-house manufacture.
Every Grand Seiko features signature high standards of Japanese precision, durability and legibility, handcrafted by Takumi artisans.
Calibre 9F82:
Offering the same functionality as the standard Calibre 9F82, Calibre 9F86 is equipped with the first GMT function of Grand Seiko.
A quartz movement depends on a battery as a power source. The battery sends electricity to a quartz oscillator, which vibrates at precisely 32,768 times per second. An integrated circuit (IC) detects these vibrations and sends out an accurate time signal every second to the step motor. The step motor activates in accordance with this time signal, accurately rotating a series of gears and the watch hands.
