Mecha-Quartz: The Hybrid Watch Movement

Mecha-Quartz: The Hybrid Watch Movement

A term that frequently appears in the watch world and yet remains a mystery to many: Mecha-Quartz. This term pops up time and again, but only a few people truly understand what lies behind it. In this article, we attempt to shed some light on Mecha-Quartz watch movements and answer some questions.

What is a Mecha-Quartz Movement?

Behind a Mecha-Quartz movement lies a sophisticated technology that combines the advantages of battery-operated and automatic movements. 
Sounds intriguing? We think so too!

But how is this possible? Inside a Mecha-Quartz movement, there are two "engines."
Hours and minutes hands are powered by a battery-operated motor, similar to a quartz watch. Seconds hands and possible chronograph modules are driven by a second, mechanical motor. Mecha-Quartz is thus a hybrid of quartz and automatic.

Mecha-Quartz: Combining the Benefits of Quartz and Automatic?!

That's right! Watches with Mecha-Quartz movements combine the advantages of quartz watches and automatic watches.

1. Precise Like a Quartz Watch

The major advantage of quartz watches over automatic ones, aside from the price, is accuracy. Quartz watches are very precise, while automatic watches depending on the movement and regulation, can have a deviation of -20 to +40 seconds per day.
A watch with a Mecha-Quartz movement is as precise as a quartz watch thanks to the embedded quartz crystal.

2. Smooth Second Hand Movement Like an Automatic Watch

Usually, we are familiar with quartz watches having a ticking second hand that moves "jerkily" second by second. In contrast, the second hand of an automatic watch moves very smoothly. 

3. The Durability of Mecha-Quartz Movements

Compared to purely mechanical movements, Mecha-Quartz watches are more robust and less susceptible to wear and tear. They are thus perfectly suitable for daily use as well.

4. Mecha-Quartz as an Affordable Alternative to Automatic

Mecha-Quartz watches offer excellent performance at an affordable price, making them an attractive option for watch enthusiasts on a limited budget. 

5. The Versatility of Mecha-Quartz

Mecha-Quartz movements enable a wide range of functions and complications, including chronographs, 24-hour displays, and much more. 

Does a Mecha-Quartz Movement have any drawbacks?

1. Battery Replacement Required

Like conventional quartz watches, Mecha-Quartz watches rely on a battery. Once it runs out, it needs to be replaced. Compared to purely mechanical watches, this is, of course, a disadvantage. However, changing the battery is a quick task for any watchmaker and is only needed every few years. 

2. Lack of Tradition 

Some watch enthusiasts appreciate the charm of mechanical watches and simply don't want to wear a battery-operated watch on their wrist. In this case, a Mecha-Quartz watch is not the right choice. 

Is a Watch with Mecha-Quartz Movement a Good Choice for Me?

The choice between a Mecha-Quartz, quartz, or pure mechanical watch depends on individual preferences and requirements. Ultimately, it's about finding the perfect watch for you, one that you find visually appealing and possesses all the functions that matter to you. 

If you find the benefits of quartz and automatic movements as fascinating as we do, then you should definitely take a look at the STERNGLAS Sedius.

Strictly speaking, the Sedius does not have a mechanical/quartz movement; instead, it features a pure quartz movement. However, what makes this movement special is the smooth second hand, typically associated with automatic watches. Therefore, quartz movements with a smooth second hand are colloquially referred to as "Mecha-Quartz." The Sedius is the first model where we have chosen such a movement, thus combining the advantages of both quartz and automatic.

Two Contrasts United in One Watch: The STERNGLAS Sedius

Bauhaus meets Art Déco: The Sedius model combines two contrasting design philosophies into a watch with a unique character.

The STERNGLAS Sedius, available in white and black color variants, features a classic sector dial that combines concentric circles with lines to create a functional, visually clear, and easily readable display. In the black variant, the gold-colored leaf hands provide a contrast to the satin-finished black and anthracite dial. Double-domed and double anti-reflective sapphire glass not only protects against everyday scratches but also ensures excellent legibility.


The duality of Bauhaus and Art Déco is also reflected in the movement: The uniqueness of the Sedius is, of course, the analog Mecha-Quartz movement VH31 by Seiko, which maintains the reliability of a quartz watch while featuring a smooth second hand movement similar to an automatic watch. Thus, the Sedius combines the functionality of Bauhaus and the stylish elegance of Art Déco.

For those who want to know more ‚Äď What's behind the exciting Mecha-Quartz movement caliber VH31?
    • Thickness: 3.45 mm
    • Diameter: 23.70 mm
    • Jewels: 2 jewels
    • Quartz Oscillation Frequency: 32.77 Hz
    • Display: Hours, minutes, and seconds are centered.
    • Accuracy: ¬Ī 15 seconds per month
    • Battery Life¬†: 2 years

Sound intriguing? Discover the Sedius model now. It's the first STERNGLAS watch that combines the advantages of quartz and automatic movements.
