3/4夾板。。。 是指隻手錶的夾板只有3/4塊, 留空1/4讓你可以看到擺輪和其他配件(亦方便為這些配件做維修)。

例如:

德國錶比較喜歡用3/4夾板。

只是順帶個問題,反正要看里面,點解仲要呢個夾板呢? 沒有呢個夾板,個背咪仲看透? 還是半個夾板, 不是看得更多? 如果太 technical 就不需要回了,只是好奇。

Allow me to quote from a web-site:

[i]"THE FUNCTION OF THE GLASHUTTE THREE-QUARTER PLATE.The three-quarter plate is one of the most important traditional elements of A. Lange & Sohne watches. It was introduced by Ferdinand A. Lange in 1864 and since then has established itself as a characteristic feature of watchmaking in Glashutte.

The three-quarter plate accommodates the bearings of the going train. During assembly, it must be accurately positioned over several arbors at the same time, a task which requires a steady hand, and a great amount of time and care. But in comparison with conventional configurations based on multiple bridges, this construction adds considerable stability to a movement. Moreover, a three-quarter plate not only allows a reduction of the axial distance tolerances of the wheels, it also makes movements more resistant to soiling, as evidenced by historic pocket watches."  [/i]

我只知道夾板數量越少越難組裝,呢個一塊過夾板裝到火都黎:smile_o02:,可能係小弟技術太差。
