请问“reversed or glittered spiral”是什么意思？

非官方网站的说法：

Compared to the ETA Valjoux 7753 self-winding chronograph caliber, the ETA Caliber H31 is equipped with a larger mainspring barrel that allowed for a much longer power reserve of whole 60 hours.

The second modification that resulted in better accuracy is a reversed (also known as “glittered”) spiral.

从整句来看应该是指反向游丝。

何为反向游丝?

这视频之前看过，唯独没提到这个“reversed or glittered spiral”。。。

The word "glitter" is often used euphemistically to refer to brilliantly gorgeous but superficial glamour. From this meaning comes the term glitterati to refer to pop stars and socialites. The word is derived from "glitter" and "literati".

维基百科：“glitter”一词有“华丽的转身”的意思，应该是指游丝上下层倒反？
