Seiko celebrating anniversaries this year as “100 years of Seiko watches”, “25 years of kinetic” and even “20 years quartz at Grand Seiko.” Willich, 2 July 2013. in 1993, Seiko introduced collection to a quartz movement in the Grand Seiko caliber 9F for the first time. Adapted to the high demands of Grand Seiko, the caliber ensures highest precision. On the occasion of the 20th anniversary of this introduction, Seiko launches an anniversary model in the summer. The SBGX103 is equipped with the calibre 9F62 and offers sophisticated design elements that reflect the anniversary. Small lion emblems and the Roman numeral XX adorn the dial and draw attention to the 20th anniversary. The lion in the direction of the index is turned, in addition to denote the anniversary at the 20-minute position. The Golden Star at 6 o’clock is for the extraordinary precision of the used caliber 9F62.
KT Yellow Gold Lion decorates the bolted bottom of the limited model an 18. The caliber of 9F runs extremely precise and hands show the time precisely. The second hand is precisely aimed at every single second marker and not swinging up. An additional regulation wheel is equipped with a spring compensates for the game between the wheels of the clockwork and prevents the vibration. The hour hand is moving 1,440 times 24 times, the minute hand and the second hand 86,400 times in the day. To ensure that the absolute precision is bothered any of these 87.864 movements by influencing the pointer between them, each pointer has an own axis. Seiko developed for direct switching of date circuit a special lever mechanism, a direct switching of date in only 1/2.
000stel sub-second guarantees. So the date to point changes currently midnight. As with most quartz watches, the oscillator vibrates 32,768 times per second. Because the frequency can be influenced by external factors and a stable oscillation behavior is crucial for accuracy, each is single quartz crystal for Grand Seiko individually selected and tested. Only after a three-month artificial aging process, these crystals achieve the precision required for a Grand Seiko. The stable and accurate vibration of a quartz crystal is also dependent on temperature fluctuations. In order to ensure the accuracy, automatically determines the caliber of 9F 540 times the day temperature changes and compensates for them. While a mechanical watch accuracy can be manually adjusted, have conventional quartz watches, no such mechanism. The caliber of 9F is equipped with a wheel for the fine adjustment and thus ensures highest precision.
