G100 La Joux Perret automatic movement
with 68-hour power reserve.

More time, more precision.

When choosing a high-quality automatic watch, the built-in movement plays a central role. It not only determines precision and longevity, but also comfort in everyday life. One particularly powerful movement that is attracting the attention of more and more watch enthusiasts and manufacturers is the La Joux Perret
G100 automatic movement with an impressive 68-hour power reserve. In this article, you can find out what makes this caliber so special and why it is also used in CiRCULA watches.

Long-lasting power reserve for modern everyday life.

The power reserve describes how long an automatic watch continues to run without being moved or wound. With a power reserve of up to 68 hours, the La Joux Perret G100 is well above the standard of comparable movements, which usually only last 38 to 42 hours. For you as the wearer, this means that even if you take your watch off for the weekend, it will continue to run reliably on Monday morning - without the need to be adjusted.

Impressive
technical data.

The La Joux Perret G100 automatic movement operates at a frequency of 28,800 vibrations per hour (4 Hz) and thus offers smooth, precise running. A special feature is the rotor made of solid tungsten. At around 19 g/cm³, tungsten has a significantly higher density than stainless steel (approx. 8 g/cm³), which gives the rotor a higher moment of inertia and thus enables more efficient energy transmission during automatic winding - even with a low movement profile.

With a diameter of 25.6 mm and a height of just 4.45 mm, the movement fits perfectly into slim cases while maintaining a high level of stability and ease of maintenance.

A high-quality alternative to established calibers.

The La Joux Perret G100 was developed in the 2000s and thus represents a modern alternative to older calibers such as the ETA 2824, which was designed back in the 1970s. With its extended power reserve of 68 hours and contemporary technical features, the G100 movement meets the requirements of modern watch brands that focus on quality, reliability and independence.

Thanks to its standard dimensions, the movement can be integrated into many existing cases - an advantage for watch brands such as CiRCULA that value technical flexibility and an optimum price-performance ratio.

Fine workmanship
and precision performance.

Another highlight of the La Joux Perret G100: the high-quality workmanship. Depending on the version, finishes such as Geneva stripes, perlage or thermally blued screws are possible - features that not only impress visually, but also indicate high manufacturing quality.

The La Joux Perret G100 combines technology, comfort and longevity.

Anyone who opts for an automatic watch with the G100 caliber benefits from a modern, robust and precise movement with an exceptionally long power reserve. It meets the requirements of watch connoisseurs who not only pay attention to design, but also to the technical heart of their watch.

At CiRCULA, we rely on the La Joux Perret G100 because it offers quality and reliability at the highest level.
