Seiko is a luxury brand that has designed a lot of premium watches. And Spring Drive is one of the groundbreaking additions. It is a great example of a state-of-the-art watch that comes with a unique movement system. 

Drive Spring watch nicely combines both mechanical and quartz timekeeping movement and eliminates the weakness of both these movements. There are many unique features you will be amazed to see. So, let’s see how does a Seiko Spring Drive watch work?

What is a Spring Drive in Seiko?

You will find a lot of different brands and types to choose from in this industry. But, a Seiko Spring Drive watch is offering something that combines both luxury appearance and unique features just like you want.  

Yoshikazu Akahane was the engineer who dreamed of an ever-lasting watch and it took 28 years to bring the dream come true. After countless setbacks and prototypes, he actually succeeded to invent new technology and bring a revolution in watchmaker’s art.

Unlike other watches, Seiko Spring Drive watches don’t use a battery. Instead, they use a mainspring, similar to those found in traditional mechanical watches.

Parts of the Seiko Spring Drive Watch

Seiko Spring Drive Watch gives more accurate time results and gives it a longer power reserve. The watch is also much quieter than a traditional watch, which makes it perfect for people who want a watch that won’t disturb them while they’re working or sleeping.

Spring Drive has a unique movement system that usually operates in four stages. Here are the parts:

  1. Mainspring: The source of energy. It works like the traditional watch mechanism.
  2. Transmission: It works to transmit the power to the gear train and tri-synchro regulator. 
  3. Tri-synchro regulator: It works to control the speed of the glide wheel. It controls the energy source, converts a part of energy into electrical power, and produces magnetic force to regulate the speed. 
  4. Magic lever: It is a unique winding system that is connected to the shaft of the rotor for efficiency and a long power reservation.

Seiko Spring Drive Watches and How it Works?

Spring Drive is a new type of movement that makes the watch long-lasting. Yet, the mechanism is simple and you can easily understand it. 

Let’s start with the power source which is the mainspring. It is a high-elasticity alloy. Then power transfers to the gear train. At the end of this part has a small disc that is called a glide wheel. When the glide wheel slows down, it releases energy from the mainspring. 

The electricity, produced by the glide wheel activates the integrated circuit and the quartz oscillator. As you know, quartz crystal is piezoelectric that provides precise frequency when electricity passes through it. 

The frequency compares the regulation speed of the glide wheel. Here the regulator works to define the speed. If the glide wheel runs too fast, the tri-synchro regulator compares the signal to the revolution speed of the glide wheel. 

The integrated circuit provides an electromagnetic brake to the wheel when the glide wheel run too fast and it shows down. The integrated circuit works like an on and off switch for the electromagnetic brake. 

Is Seiko Spring Drive any good?

A Seiko Spring Drive contains a mainspring that powers a gear train, similar to a traditional mechanical watch.

The watch’s hands move continuously, in a sweeping motion, rather than ticking. The motion is generated by a glide wheel which is rotated by the mainspring. 

The glide wheel in turn rotates a magnet, which induces an electrical current in a coil. This current is used to power an electromagnet, which brakes action on the glide wheel, controlling the watch’s rate.

The watch is quite expensive, but it is worth buying for its incredible features and luxury appearance. Here are the key factors that make the watch the best popular of all.  

  • When it comes to luxurious timepieces, few brands can rival Seiko. The Japanese company has been making high-quality watches for over a century, and their craftsmanship is evident in every timepiece they create.

    But Seiko is not content with simply making beautiful watches – they are constantly innovating and pushing the boundaries of watch design.
  • The primary benefit of a Spring Drive is its accuracy. The use of an electromagnet, rather than a mechanical escapement, to control the speed of the glide wheel results in a watch that is accurate to within one second per day, or much more precise than a traditional mechanical watch.
  • Another benefit of the Seiko Spring Drive is that it doesn’t require any regular maintenance. Unlike battery-powered watches, you’ll never have to worry about changing the battery in your Seiko Spring Drive watch.

    All you require to do is keep it wound and it will continue to work flawlessly for years to come.
  • Seiko’s Spring Drive Watch Work has a long and interesting history. Seiko first released the Spring Drive Watch Work in 1999.

    The watch was a big hit, and Seiko released several different versions of the watch over the next few years. The watch quickly became popular with watch collectors and enthusiasts.
  • In 2003, Seiko released the first ever Spring Drive Watch Work with a power reserve indicator. This was a major innovation, and the watch became even more popular with collectors.

    Seiko has continued to release new and innovative Spring Drive Watch Works over the years. The brand has become synonymous with high-quality and innovative watch design.
  • One of their most impressive creations is the Spring Drive watch. This watch utilizes a unique self-winding movement that is both accurate and power-efficient. The result is a timepiece that is not only a pleasure to look at, but also a pleasure to wear.

    If you’re in the market for a luxurious watch, the Seiko Spring Drive should definitely be at the top of your list.

Frequently Asked Questions (FAQ)

How accurate is the Seiko Spring Drive?

Seiko Spring Drive watches are popular for their accurate time-telling. Its tri-synchro regulator controls the mechanical power and energy and replaces the escapement with its one-way motion. So the result is more accurate and precise. It gives accuracy 1 second per day. 

Does Spring Drive have a battery?

No, Spring Drive doesn’t have a battery which is the most interesting factor of the watch. This watch automatically generates power through the mainspring and there is a reservation of 72 hours. So this watch doesn’t require a battery. 

How long do Spring Drive movements last?

Since Spring Drive works with automatic motion, many are confused about their lifespan. But let me tell you, Spring Drive watches contain premium quality. So it will last for years without any maintenance. 

Is Grand Seiko as good as Rolex?

Compared to Rolex, Grand Seiko has the standard quality to beat Rolex. Each of them has its advantages. So it is totally upon you and your personal preference as to which one you prefer. Moreover, if you are one of the watch collectors, then you can get both. 

Is Spring Drive an automatic watch?

Spring Drive is an automatic watch. It has a very organized movement system. Through the Spring Drive movement, the watch works continuously with precise accuracy.

It doesn’t require any battery. It generates electricity power by itself and keeps time with accuracy using quartz movement. 


Seiko has launched some incredible exclusive watch models in the luxury watch market. Spring drive model is one of them. Their top-notch design and unique features grab the attention of watch enthusiasts.
