还哑谜呢,这个东西鬼佬已经有评论,你有不同的看法就说出来啊,不管对于错我们都愿意听的。
不就是一个同轴擒纵嘛,一百多年前就已经有人做了,没有秘密了。
说一个关于这个机芯的小故事吧,为啥用了双游丝:
为了增加这个机芯的动力天数(168小时),设计师降低了摆频,选为21600bph,并且选择了大型摆轮,
但是找不到合适的游丝,被迫有了双游丝,这么巧(当然参考了前人的做法)得到了宝玑游丝的效果,属于歪打正着。
故事来源:
Reportedly this solution was born by necessity; having already chosen a large high inertia balance wheel, it was found that a matching hairspring was not readily available. To start right away, with height not being an issue in this specific design, the watchmakers at Renaud & Papi simply assembled two weaker but available hairsprings one on the top of the other. Instead of being a poor replacement for the 'real thing' it worked extremely well and eventually was chosen for the final design!
