COSC天文台錶證書

瑞士官方天文台檢測機構(COSC)認證是國際公認最權威的榮譽之一,印證腕錶的精確性能。

  • 保固

    這枚時計搭載的高精準機芯已通過獨立檢測機構COSC官方認證,授予其天文台錶稱號。機芯品質有目共睹。所有 Certina天文台錶可因此享有自購買日起共三年的延長保固。

  • 瑞士官方天文台檢測機構(COSC)

    著名的瑞士官方天文台檢測機構(COSC)於1973年成立,總部設於瑞士拉夏德芬(La Chaux-de-Fonds)。COSC是瑞士製錶業的獨立公共機構,測試要求極其嚴格,一致公認為評估現代機械或石英機芯腕錶精確度的標準。

  • 石英天文台錶

    COSC證書是全球公認的精確度典範。所有交至COSC檢測的石英機芯均須在不同溫度下通過嚴格測試,在攝氏23度下最大可允許運行速率偏差為每日+/-0.07秒;在攝氏8度和38度下的精確度偏差則為+/-0.2秒。Precidrive™機芯輕鬆達標,通過所有測試,因此由2017年起所有雪鐵納石英腕錶均配置Precidrive™機芯,並附有瑞士官方天文台表證書。

  • 自動天文台錶

    COSC對現代時計的性能要求非常嚴謹。所有自動(自動上鏈)腕錶均須在15天內於三種不同溫度及多個位置接受測試,準確地量度和記錄運行速度偏差。為成功獲取難得的「天文台錶」稱號,機芯的運行速度必須精確至每日-4/+6秒。
