Watch Movement / Caliber / Calibre


Although more and more watch manufacturers design and produce their in-house movements for their wrist watches, many Hearts of the watches are still "transplated" from others.

Some Hearts many be modified or finely polished before putting into the case and the Model Numbers of the movements will be amended at the same time. Therefore, the movements are upgraded and can be sold at much higher price.

We would like to introduce some of the "Hidden" Manufacturers of the Calibers in the World of watch:



Founded in 1950

Sellita is an independent Swiss company and a specialist in assembling "Swiss Made" mechanical automatic watch movements.

Being aware of the technology changes in a competitive market, Sellita decided to develop and produce their own mechanical movements in 2003.



Valjoux (for Vallée de Joux, "Joux Valley") was a Swiss manufacturer of mechanical watch movements.

It is known primarily for chronograph ébauche movements that were used in a number of mid- to high-range mechanical watches.

The company is under ETA now. In other words, it is a member of the Swatch Group. Therefore, the model number of its movements become starting with ETA.

e.g. Vajoux 7750 becomes ETA 7750


Swiss movement manufacturer ETA SA has been developing and producing calibres for the watch industry since 1793.

This expertise laid the foundations for the emergence of one of the world's largest manufacturers of watches and movements. From research and development (R&D) to global service, every quartz and mechanical movement receives our utmost attention in terms of both materials and quality.

Precision, reliability and level of performance are the key features of her products.




Miyota belongs to Citizen Watch Co. Ltd. which is one of the leading watch manufacturers in Japan.

Miyota provides high quality watch movements to other watch manufacturers which do not have the ability to produce watch movement.



Epson is a Japanese company. It produces Quartz movement.




Beijing Watch Factory Company

It was established in Changping, Beijing in June 1958.

Beijing Watch Factory was one of the major developers of the Chinese Standard Movement.
