COSC 天文台认证

瑞士官方天文台认证腕表检测机构的标识是全球范围内精准走时的权威象征。

  • 质保条款

    本时计搭载的高精准机芯已经由独立测试机构COSC官方认证为精密天文计时器。该机芯的品质之高显而易见。因此所有的雪铁纳精密天文表自购买之日起具有三年的延长保修期。

    著名的瑞士官方天文台认证腕表检测机构(“Contrôle Officiel Suisse des Chronomètres”,简称COSC)1973年创立于瑞士拉绍德封。这是一家致力于弘扬瑞士制表艺术的独立公共机构。它的严苛标准被视为评价现代腕表(不论机械机芯还是石英机芯)走时精准程度的标杆。

  • 石英机芯天文台认证腕表

    COSC 认证是精准时计全球公认的象征标志。所有石英机芯须在多种温度下进行严格的检测。这项认证要求石英腕表在23°C下,每天的最大误差不超过+/- 0.07秒;在8°C和38°C下,不超过+/- 0.2秒;雪铁纳的Precidrive™机芯可轻松满足这些严苛标准。从2017年开始,雪铁纳的所有石英表款将全部搭载Precidrive™机芯,并获得瑞士官方天文台认证。

  • 自动机芯天文台认证腕表

    COSC 对现代时计设备的要求非常高。所有自动(上链)机芯腕表需在三种不同温度和多种不同佩戴姿势下进行为期15天的检测;工作人员会严格测量并记录每种情况下的走时误差。只有每天的走时误差不超过-4/+6秒的腕表方可荣膺宝贵的“天文台认证腕表”称号。
