The Liaocheng caliber G2666Z is a skeletonized 3-hander, time-only automatic movement.

You may see this calibre listed as being made by “Hong Tai” but it seems that the rest of the factory name got lost in translation: Shandong Liaocheng Zhong Tai Watch Co., Ltd.

G2666Z movements are also distributed by PTS-Resources, which refers to them simply as “Liaocheng”, therefore, that’s what Caliber Corner will call them as well.

There is also a G2666ZH which appears to be the gold tone version.

Although this caliber is technically a skeleton dial movement, it is not uncommon for it to be used with solid dials, such as on the Benyar Aliexpress homage watches.
