Chien Chien Co., Ltd. has been in the business of manufacturing and selling watches for over 30 years. Our company not only manufactures watches for self-owned brand but also
OEM watches for big brands.

With high quality products, excellent services and a good reputation, we have won great support from customers and become more powerful. Thus, our company scale has been
expanded.

Based on over 30-year experience in the manufacture, we start manufacturing other self-owned brand products-ProKun power banks, to extend our service in the new field.

We also accept OEM and ODM orders, or other orders for manufacturing watches and power banks. Our products are in good quality and fair price, and we provide good services as
well. We are looking forward to even greater cooperation with overseas customers based on mutual benefits. Please feel free to contact us for more information.
