Swiss movement VS. Japanese movement

When we talk about or plan to buy a watch, there is always a topic that cannot be avoided and that is the watch movement. Because the movement is the heart of a watch, it is especially important to know about the movement and to understand Swiss movement VS. Japanese movement.

1.what is a watch movement

The watch movement is the important part of the watch inside of watch case.the movement drive the hand on the watch dial and make the hand beat.

The movement is the heart of the watch, like the engine of a car or the CPU of a computer, and is the core part is also different.

For example, an automatic mechanical movement is a self-winding watch that uses the power generated by the left and right oscillation of the rotor at the bottom of the movement to drive the winding to generate energy. A manual mechanical watch uses the winding as the prime mover of power, and a set of gears to drive the escapement regulator.On the other hand, quartz movement watches are powered by a battery, which generally lasts from 24 to 36 month depending on the movement used in the watch

1. What is Japan movement

Japanese movementThe Japan movt definition is a movement whose brand is from Japan.Note that not all Japanese movements are manufactured in Japan. Some are also made in Thailand, Singapore, etc. And the best Japanese brands are Miyota movement, Seiko movement, etc.

Movement types are divided into quartz, manual mechanical movement, automatic movement, optical energy, etc.For example,S of Japan Seiko PC21S means in Singapore.J of Japan Seiko PCS21J means made in Japan.

2. What is Swiss movement

Swiss movements are defined as: the assembly of the movement is done in Switzerland; the final testing of the movement is also done in Switzerland.Swiss movement

The price of the Swiss original in the movement is at least 50% of the price of all the parts.

Pay special attention that if the movement is made in Switzerland, but the finished watch is not assembled in Swiss.The word Swiss can only appear on the movement, if you want to use it on the watch face or case cover, you can only use SWISS MOVT or SWISS MOVEMENT.

3. what’s the difference? Swiss movement VS. Japanese movement


Swiss movement VS. Japanese movementSwiss movements will have a larger center axis, such as Swiss ETA's automatic tourbillon, while Japanese watch movements such as Citizen's will have a smaller center axis.

In terms of the number of seconds

Swiss movement: ETA movement is generally 8 times per second.

Japan movement: Citizen 3 times per second, other Japanese movements are generally 5 times per second

The Error

Swiss movt: the most important feature of ETA movement is very stable,accurate time and two-way winding. 28,800 times / hour frequency are able to ensure accurate time

Power reserve up to 40 hours and the 1 month error is just about 2 minutes (2 minutes faster or 2 minutes slower).

If you can do proper maintenance such as 8 years maintenance oil wash once, the life time can more than 60 years.This Swiss watch can be used as a family heirloom.

Japan movt: generally Japan movement is with 21 or 24 diamond.The oscillating frequency is 21800 and of Japan movt feature is one-way winding.

Generally speaking Japan movements need to be maintained once every 3 or 5 years.

Maintenance means oil washing or winding.

Manufacturing Process

Japanese movements are more focused on accuracy and effectiveness and cost saving. That's why the production process of Japanese movements is done on automated robotic production lines.So Japanese movements generally do not have a complex appearance and are cheaper than Swiss movements, but the quality is just as high.

On the other hand, Swiss movements are concerned with aesthetics and artistic beauty.

From the jewelry color and shape which the way it is cut,every detail is taken into account during the design and manufacturing process.That’s why many Swiss movt need hand assembled .

The history

Swiss watchmaking have a much longer tradition of history. The Swiss have been making clocks and timepieces since the 16th century. And it wasn't until the 20th century that Japanese movements began to be taken seriously and fought their way forward to catch up. By the late 1970s, Seiko mass-produced the first quartz watches, thus sparking a quartz revolution .

4. Which is better: Swiss or Japanese movement?

It is difficult to directly compare Swiss and Japanese movements because of the vast differences in design, manufacture, assembly and decoration of each movement.

Generally speaking, there is not much difference between Swiss and Japanese movements from a technical point of view.

So you can choose a movement according to your budget. Japanese movements strike a balance between affordability and quality, so you can choose a Japanese movement if you have a limited budget. If you want to use a watch for a long time (passing it from one generation to another), you can choose a Swiss movement.

Swiss movements are much more expensive than Japanese one If the movement is similar in function. For example, Seiko 7S26 and Valjoux 7750, the latter is many times more expensive.

Final thoughts:Japanese VS. Swiss movement

In general, both Swiss and Japanese movements are high quality and both are durable. so the watchmakers around the world use their movements. In watchessy, we offer both movements to customize your favorite watch according to your budget.
