Shandong Liaocheng Zhong Tai Watch Company

From Chinese Watch Industry Wiki

The Liaocheng Watch Factory was one of many enterprises founded in the 1970s for the manufacture of watches with the Chinese Standard movement under the brand name ‘Taishan’. Privatized in 2004 as the Shandong Liaocheng Zhong-Tai Watch Company, the company now works in close partnership with PTS Resources, Hong Kong in the manufacture of mechanical wristwatch movements.

This company pioneered the distinctive Chinese style of open-heart movement with the ML-7101, favoured by Million Smart Enterprises for many of their early OEM watches for international brands. It remains one of the world’s most popular open-heart movements. This success was followed up by the more visually-striking F and M series of open-hearts. Liaocheng Watch Company also manufactures skeleton and dual-mainspring movements.
