手表的后盖对于手表可以起到很好的保护作用
防止灰尘和水进入手表内部，有些机械表后盖是透明的，到底这样好不好呢?
我们看下面的介绍。
凡精细奥妙的东西，就应该展示给人看。手表机芯在结构原理和加工制造上是很耐看，精致打磨的零件也非常美，同时也可以窥测到手表每一操作的动作过程，这也是机械手表的魅力所在。透底的手表对机芯表面的修饰有很高的要求，比如自动陀、轮夹板，一般都用条形纹、珍珠纹、弧线纹来修饰。
透底的手表的玻璃基本上都采用蓝宝石玻璃，从接触人的手腕皮肤的考虑，还能大大的减少不锈钢中的镍金属渗出，从而减少对人皮肤的可能的过敏影响，比较绿色健康。**不利的是透底的手表防水密封圈要多一道，做到手表密封就更困难些。
透底的手表机芯表面甚至内部(包括：机芯标识、号码、防震器等)可以看的一目了然， 因此更不容易被做成假表。它的走时状态(比如：摆轮的振幅，自动陀的旋转) 也能方便的观察到，这也是一个好处。

Watch the back cover to watch can have very good protection effect

Gone watch for movement requires a high degree of surface modification, such as automatic tuo, round of plywood, with bar lines, pearl grain, curve grain to modify.
Trainspotter watch basically adopts sapphire glass, considering from contact with a person's wrist skin, also can greatly reduce the nickel in the stainless steel metal seeping, thus reducing the impact on the people may be skin allergy, more green and healthy.

Trainspotter watch movement of surface and internal (including: movements, as well as identification number, shock absorbers, etc.) can see at a glance, therefore less likely to be made into fake ones. The amplitude of its walking state (such as: balance wheel, automatic the rotation of the vedas) can be easily observed, this also is a benefit.
The above is our technician is a simple introduction, hope will be helpful to you. If you have any need or have any doubt, make free calls, consulting.
