How to Distinguish A Watch Between A Swiss movement and A Japanese Movement


How to distinguish a mechanical watch from a Swiss movement or a Japanese movement? Swiss brand mid-end watches and domestic brands of high-end mechanical watches generally use Swiss ETA movements, mainly ETA2892, 2836 and 2824.

Watches with Japanese movements are generally Citizen and Seiko movements, with 9015, 8215, 8205, and NH35 as the main watch.(Know more about the watches movement:THE TYPES OF WATCHES MOVEMENT)

Watches movement identification can start from three aspects:


First of all, from the appearance of   Swiss movement and  Japanese Movement.

The center axis of ETA's movement is larger, the automatic rotor is larger than the ordinary, and the axis of the automatic rotor is also larger. The Citizen and other Japanese movements are significantly smaller.

Secondly, from the  beats times of the second hand in Japanese Movement watch and Swiss movement watch.

 

The ETA movement is generally 8 times per second, the Citizen 3 times per second, and other Japanese movements are generally 5 times per second.


Finally, In the process of use, the errors produced by the Japanese movement and the Swiss movement watch are different.

 

The biggest feature of the ETA movement is stability, accurate travel time, and two-way winding. The swing frequency of 28800 times / hour ensures accurate travel time, and the power reserve is up to 40 hours and a month error of about 2 minutes ( It is 2 minutes faster or 2 minutes slower). If it is stored properly (8 years maintenance and washing oil once), the service life is more than 60 years at all; so people who know the watch will say that when you wear a watch, you wear a Swiss watch!

Japanese movements are generally used for mid-end watches of domestic brand watches; because movement prices are not high, they are all equipped with Japanese mechanical movements, and only high-end watches are equipped with Swiss mechanical movements. The Japanese movement is generally 21 diamonds, 24 diamonds, swing frequency 21800 and 28800, one-way automatic winding; and maintenance once every 3 to 5 years (oil washing or clockwork).

 

 Of course, the quality and price of watches with different movements are not the same, we should choose the right watch for us. If the quality of a watch with a Japanese movement is good, and the price is not high, we can also say that it is a watch which is good and inexpensive and worth buying.
