Arnold & Son Perpetual Moon 41.5 Red Gold – Cliff Grey Edition

JUNE 24 2025    |    Novelties

Arnold & Son unveils the Perpetual Moon 41.5 Cliff Grey Edition, a poetic tribute to the cliffs of Cornwall and the legacy of John Arnold, the renowned marine chronometer-maker. This limited edition of 28 pieces in 18-carat red gold reflects the brand’s deep connection to celestial navigation and English heritage.

The dial is adorned with the exclusive Stellar Rays motif, a textured pattern that plays with light through layered transparent lacquer. Its Cliff Grey tone evokes the misty British coastline, while the moon phase display—among the largest in watchmaking—glows in mother-of-pearl enhanced with Super-LumiNova. Set against a midnight-blue sky, the moon is surrounded by hand-painted constellations, Ursa Major and Cassiopeia, symbols of guidance and exploration.

The case, measuring 41.5 mm in diameter, is sculpted with refined lugs and a slim bezel that opens up the dial to its full celestial display. On the reverse, a secondary moon-phase indicator allows for precise adjustment of the moon’s age.

Inside, the manually wound A&S1512 calibre offers a 90-hour power reserve and tracks lunar cycles with remarkable precision. So accurate is its mechanism that it would take 122 years of continuous operation to accumulate a single day’s deviation from the actual lunar cycle.

Crafted entirely in-house in La Chaux-de-Fonds, the movement is finished with Geneva stripes, blued screws, and circular graining. The watch is completed with a warm grey alligator leather strap and a matching red gold pin buckle.

The Cliff Grey Edition is a refined expression of Arnold & Son’s dedication to craftsmanship, astronomy, and timeless design.

Timeless Precision: Greubel Forsey’s QP Balancier Redefines the Perpetual Calendar

Greubel Forsey proudly unveils the QP Balancier, a revolutionary interpretation of the perpetual calendar that merges intuitive functionality with uncompromising chronometric performance. Limited to just 22 pieces in white gold, this timepiece represents a new pinnacle in haute horlogerie.

At the heart of the QP Balancier lies Greubel Forsey’s patented Mechanical Computer, a 25-part mechanical brain that “understands” the rules of the Gregorian calendar. This innovation allows the watch to adjust instantly in either direction, restart flawlessly after months unwound, and remain programmed until February 28, 2100—all without the need for pushers or complex crown positions.

The QP Balancier integrates 12 indications—including hours, minutes, seconds, power reserve, day, date, month, leap year, day/night, 24-hour display, calendar year, and a patented function selector—into a single crown interface. This makes it the most user-friendly perpetual calendar ever created, eliminating the need for manuals or reset tools.

Aesthetically, the watch is a study in purity and harmony. Its multi-level gold dial presents calendar information in a clear, linear format, flanked by leap year and day/night indicators. The tactile feedback during quick-correction mode offers a unique sensory connection between wearer and mechanism.

Housed in a 45.1 mm white gold case, the QP Balancier features Greubel Forsey’s signature 30° inclined balance wheel, a high-mass, variable-inertia system with gold mean-time screws. The movement comprises 612 hand-finished components, including twin fast-rotating barrels that deliver a 72-hour chronometric power reserve.

With the QP Balancier, Greubel Forsey has not only redefined the perpetual calendar—it has perfected it.

Moritz Grossmann Announces the TEFNUT 36 Silver-Plated by Friction Turquoise Blue

oritz Grossmann celebrates the 200th birthday of its founder with the launch of the TEFNUT 36 Silver-Plated by Friction Turquoise Blue, a timepiece limited to just 12 pieces worldwide. This special anniversary edition combines traditional 19th-century craftsmanship with a modern aesthetic, paying homage to the visionary watchmaker, scientist, and founder of the German Watchmaking School. The manufactory in Glashütte continues to honor this rich heritage by blending historical techniques with contemporary design.

The dial of the watch is crafted using a meticulous silver-plating by friction technique, also known as silver-plating by grit, which is executed entirely by hand through multiple complex steps involving silver powder, salt, tartar, and water. This traditional process imparts a velvety, matte structure with remarkable optical depth, further enhanced by a unique green-tinged blue hue that shifts dynamically depending on the angle and lighting. Contrasting the textured surface are engraved Roman numerals lacquered in blue, alongside the historic 1875 'M. Grossmann' logo, scale markers, and manually crafted steel hands annealed to a vibrant blue hue.

Housed in a slender and expressive 36-millimeter stainless steel case with a flat profile, the watch is designed to offer exceptional comfort and elegance on any wrist. It is complemented by a hand-stitched grey kudu leather strap featuring a pin buckle in stainless steel. Inside ticks the manufacture calibre 102.1, a hand-wound mechanical movement measuring just 3.45 millimeters in thickness, featuring a pillar movement architecture, a three-fifths plate, a stepped balance cock with a Grossmann micrometer screw, and a special '1826' anniversary engraving.
