看到前面在討論ETA洗油的問題
推文裏提到同是ETA機芯的差異
於是就好奇拜了一下大神
果然長了知識
分享一下
光是ETA 2824-2
就分四種等級:
標準級STANDARD GRADE:
2方位調整,調整日差正負12秒,單日最高誤差正負30秒
精製級ELABORATED GRADE:
3方位調整,調整日差正負7秒,單日最高誤差正負20秒
頂級TOP GRADE:
5方位調整,調整日差正負4秒,單日最高誤差正負15秒
時計級 CHRONOMETER:
符合COSC規範,並附有檢測證明
用料方面也稍有不同 (翻譯不對的話請指教)
標準級和精製級:
發條-Nivaflex NO
套筒-Nivatronic
擺輪-鍍金鎳
游絲-Nivarox 2
平衡擺輪-Epilame塗層
避震-Etachocs
Pallet Stones-Polyrubies, Epilame-coated
游絲熱處理-Etasable
頂級和時計級:
擺輪-Glucydur鍍金
套筒-Nivatronic
發條-Nivaflex NM
避震-Incabloc
游絲-Anachron
平衡擺輪-Epilame塗層
游絲熱處理-Etasable
Pallet Stones-Polyrubies, Epilame-coated
基本上
TOP和CHRONOMETER用料完全相同
差異在於
CHRONOMETER每一個機芯都有獨立序號,且有COSC證書
我的理解大概是這樣
結論是
就算平平是滿地都是的ETA 2824-2
除了外觀打磨之外
確實在用料和調校上有等級之間的差異
各廠自己魔改的不在討論範圍內
以上歡迎指教 :)
