Introduction
The Haute Horlogerie world is abuzz with the latest release from independent watchmaker Henri Grandjean—the Magician Atrivm. Unveiled just prior to the Geneva Watch Days 2026, this exquisite timepiece is a triumph of craftsmanship and innovation, featuring a striking case made from both green and red sapphire.
Design and Construction
The Magician Atrivm distinguishes itself not only through its stunning aesthetic but also its technical prowess. The watch showcases a fully transparent sapphire crystal case that allows for an unobstructed view of its intricately designed internals. Available in Green Sapphire and Red Sapphire, these cases are a nod to the vibrant colors that have become increasingly popular in high-end watchmaking.

Moreover, the watch features a Grand Feu Enamel dial, which is renowned for its depth and vivid color, making this timepiece both a collector's item and a work of art. The combination of these materials and techniques elevates the watch to a level of luxury that appeals to discerning enthusiasts and collectors alike.
In terms of dimensions, the Magician Atrivm measures 45 mm in diameter and is 16 mm thick. This substantial size offers a commanding presence on the wrist without becoming overly cumbersome, adhering to the modern trend of larger timepieces while still maintaining elegance.
Movement
At the heart of the Magician Atrivm lies the Calibre 1831 movement. This manual winding movement is particularly noteworthy for its triple-axis tourbillon. The tourbillon serves to counteract the effects of gravity on the watch's movement, enhancing its accuracy. The complexity of such a mechanism is a hallmark of haute horology and speaks to the technical prowess of Henri Grandjean as an independent watchmaker.

This movement not only displays advanced engineering but also allows for functionalities that include hours, minutes, a central date, and day-night indications. Such features assure that the watch is as practical as it is luxurious, aligning with modern needs in timekeeping.
Water Resistance
The Magician Atrivm holds a water resistance rating of 3 ATM, which means it can withstand incidental contact with water, making it suitable for everyday wear. However, prospective buyers should note that this level of water resistance does not recommend the watch for swimming or diving. Instead, it is more suited for formal occasions where splashes of water are likely to occur, thereby maintaining its aesthetic integrity.
Pricing and Availability

This premium comes not only from the materials used, but also from the exceptional craftsmanship that goes into each timepiece, making it a desirable item for collectors looking to invest in a piece of horological artistry.
Conclusion
The Henri Grandjean Magician Atrivm in Green and Red Sapphire is more than just a watch; it is a statement piece that encapsulates the essence of luxury and sophistication in modern watchmaking. With its breathtaking design, complex movement, and luxurious materials, it represents an investment into the world of haute horlogerie.
