Powered by a Quartz caliber 9F86, this Sport timepiece by Grand Seiko is water resistant up to 100 meters and is equipped with magnetic resistance.
Housed by a durable 39mm stainless steel case and presented on a coordinating stainless steel bracelet, the blue sun-brushed dial is set beneath sapphire crystal glass for protection and equipped with a date display window at 3 oÕclock, a 24-hour hand for dual time display and luminescent hands and hour markers for optimal visibility.
Calibre 9F86:
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.
