List of PTS Resources Calibers

PTS Resources (partner with Hangzhou Watch Company), is based in Hong Kong with offices in Shenzhen and Guangzhou.

Made in China watch movements are painstakingly difficult to research and organize. It’s not unusual for movements from Chinese factories to be unmarked (no brand, no caliber number, no jewel count), with very little technical information available to the public. To make things more confusing, there was a time when PTS Resources also listed calibers from other brands in their official catalogs (for example, S.Epson quartz movements). It is unknown if they simply supplied those movements on behalf of other companies, or if they manufactured them in partnership with the other brands.

The list below is an ongoing collection of known PTS Resources watch movements. More will be added as the community comes across them.

Some of the topics covered in this caliber listing:
