刚才去wikipedia搜索了一下Meisterstück的含义
Meisterstück is the flagship line of pens from luxury brand Montblanc. Although principally concerned with writing instruments, the brand has of late used the Meisterstück name in association with members of its diversified product range including watches, jewelry and leather goods.第一句的意思就是大班系列(Meisterstück)属于万宝龙旗下钢笔系列的旗舰级的产品线。所以，根据我的理解，我觉得万宝龙已经把最新的产品线的宣传文案做了调整，现在，或许只有美耐华机芯和万宝龙自产的机芯可以印Meisterstück，而所有的非自产机芯都不会再在摆陀上印上Meisterstück的字样了。
