要想说明什么是逆跳表,恐怕得先说明人们为什么需要逆跳表。对于绝大多数人来说,逆跳表的功能实在可有可无——它不能显示除了时间之外更多的信息,它也不能让手表的计时变得更加准确,它更不能延长手表的寿命。要知道,当一块腕表采用了逆跳的功能之后,腕表内部的撞击次数是非常多的。以30秒逆跳而言,一天之内,表内机械结构必须承受2880次的弹跳返回动作,其机芯内逆跳机制的各项零组件受到的应力是相当频繁而且巨大的,因此在设计上必须非常注重稳定性与能否承受巨大应力等严肃课题。
To explain what is retrograde, I am afraid to explain why people need to retrograde. For the vast majority of people, retrograde table function is dispensable - it can not display more information than time, it can not make the watch more accurate timing, it can not extend the watch’s life. You know, when a watch with a retrograde function, the watch’s internal impact is very much. To 30 seconds retrograde, in a day, the mechanical structure within the table must withstand 2880 bounce back action, the movement within the movement of the components of the inverse jump mechanism is quite frequent and huge, so in the design We must attach great importance to the serious issues such as stability and ability to withstand huge stresses.
