La Joux-Perret G100: A Modern Alternative to Swiss Watchmaking Icons

When it comes to mechanical watch movements, few names are as recognizable as ETA, Sellita, and Miyota. However, in recent years, La Joux-Perret has been making waves in the industry with its caliber G100, a movement designed to rival the well-known ETA 2824 and Sellita SW200.

At DWISS, we have chosen the La Joux-Perret G100 for our Model A1, an automatic Swiss-made timepiece that represents the perfect balance of precision, reliability, and innovation. In this article, we will dive into the technical specifications, history, and advantages of this movement, as well as compare it to other competitors in the market.

A Brief History of La Joux-Perret

La Joux-Perret is a Swiss movement manufacturer based in La Chaux-de-Fonds, a city known for its deep-rooted watchmaking traditions. Originally founded as Jaquet SA, the company was renamed La Joux-Perret in 2004 and later acquired by Citizen Group in 2012. This acquisition allowed the brand to expand its production capabilities while maintaining its Swiss heritage.

Known for producing high-end complications and movements for brands like Hublot, Girard-Perregaux, and Arnold & Son, La Joux-Perret specializes in creating both proprietary and modified calibers. The G100 is one of their most well-known automatic movements, offering a robust alternative to some of the industry’s most widely used calibers.

Technical Specifications of the La Joux-Perret G100

The G100 is designed to be a high-performance automatic movement with modern upgrades over classic Swiss calibers. Here are the key specifications:

• Diameter: 25.60mm
• Height: 4.45mm
• Jewels: 24
• Frequency: 28,800 vibrations per hour (4 Hz)
• Power Reserve: 68 hours
• Hacking: Yes
• Winding: Unidirectional automatic
• Accuracy: Expected to be within -4/+6 seconds per day (COSC-certified versions available)

Compared to movements like the ETA 2824-2, which offers a 38- to 42-hour power reserve, the G100 stands out with its impressive 68-hour reserve. This makes it an excellent choice for wearers who may rotate between multiple watches, as it can sit idle for nearly three days without needing to be reset.

The Advantages of the La Joux-Perret G100

1. Extended Power Reserve

One of the most notable features of the G100 is its extended power reserve. At 68 hours, it offers nearly twice the autonomy of traditional Swiss calibers like the ETA 2824 and Sellita SW200. This improvement makes it more convenient for daily wear and better suited for those who alternate between watches.

2. High-Quality Finishing

La Joux-Perret is known for its excellent finishing, and the G100 is no exception. The movement is available in different finishing grades, ranging from industrial-level decorations to beautifully perlage and Geneva-striped versions. Brands can choose a finishing style that complements their timepieces, adding to the watch’s overall aesthetic appeal.

3. Availability and Independence from ETA

With the gradual reduction of ETA movement supply due to Swatch Group’s restrictions, many brands have sought alternatives. The G100 serves as a strong competitor, giving watchmakers an independent Swiss option without compromising on quality or performance.

How the G100 Compares to Other Popular Movements

La Joux-Perret G100 vs. ETA 2824-2

The primary advantage of the G100 over the ETA 2824-2 is its extended power reserve. While the ETA 2824-2 remains a reliable choice, the G100 offers modern enhancements that improve usability and convenience.

La Joux-Perret G100 vs. Sellita SW200

Sellita’s SW200 is an excellent alternative to the ETA 2824-2, but it doesn’t quite match the power reserve of the G100. The G100’s longer reserve makes it a more attractive option for many modern timepieces.

Brands Using the La Joux-Perret G100

The G100 is used in a growing number of watches across various brands, including:

• DWISS Model A1 – A Swiss-made automatic watch known for its unique design and modern engineering.
• Anordain Model 2 – A handcrafted enamel-dial watch that benefits from the G100’s high power reserve.
• Norqain – A young Swiss brand incorporating La Joux-Perret movements in some of their offerings.

Final Thoughts

The La Joux-Perret G100 is proving to be a formidable alternative to traditional Swiss movements like the ETA 2824-2 and Sellita SW200. With its extended power reserve, excellent finishing options, and reliable performance, it offers a modern take on automatic watch calibers.

At DWISS, we are proud to incorporate the G100 into our Model A1, ensuring our customers experience both quality and innovation in every timepiece. As the industry continues to evolve, movements like the G100 represent the future of independent Swiss watchmaking.

Whether you are a collector, enthusiast, or someone looking for a reliable and high-performance watch, the La Joux-Perret G100 is certainly a movement worth considering.
