Moon Phase 37MM Steel

Égérie Moon Phase – High-Grade Stainless Steel Chassis and Integrated Metallic Bracelet Architectural Identity

The structural case framework projects absolute aesthetic authority through its fluid circular contours, achieving an ultra-feminine 37 mm diameter scale and an elegant dress thickness profile of 10.23 mm to express an uncompromised jewelry presence on the wrist. The entire integrated body and polished fixed bezel are masterfully sculpted from premium Stainless Steel—combining high-performance durability with a refined, sharp masculine aesthetic. The fixed bezel track is beautifully illuminated by ancestral gem-setting mastery, holding 58 round-cut diamonds that trap and diffuse ambient reflections with exceptional rate stability.

Elevating its functional comfort, this execution arrives paired with a matching premium solid Stainless Steel link bracelet. The high-grade brick layout combines precise vertical satin-brushing with high-contrast hand-mirror-polished surfaces, letting the metal mesh flow seamlessly to wrap around the contours of the feminine wrist with infinite lightness, like a second skin. The architectural shell features a highly original off-centered winding crown positioned between 1 and 2 o’clock (exactly at 1:30), topped with a smooth, natural moonstone that projects an ethereal lunar glow. The reverse exhibition window exposes the hand-decorated mechanical execution of the movement through a sapphire view shield, secured tightly to satisfy a daily-resilient 3 bar (30 m) water resistance.

Pristine Silver Opaline Façade Intertwined with an Asymmetrical Diamond Moon Phase Ring

The visual dial canvas is beautifully laid bare across its highly customized, silvered opaline face, executing a delicate pleated pattern structure achieved through the specialized métiers d’art tapestry technique to mimic sunray-fan pleated silk textiles. The technical interface divides its temporal indicators across a fluid, asymmetrical arrangement: applied 18K gold cursive Arabic numerals glide alongside central leaf-shaped hours, minutes, and sweep seconds pointers, adding a high-couture tailored touch to the dial layout.

The crowning complication window beats majestically at 1:30 along the off-centered crown axis, creating an unmatched astronomical stage. A delicate solid 18K gold ring set with 36 round-cut diamonds (~0.1cts) encircles the celestial complication theater. Inside this mechanical aperture, twin gold moon discs navigate smoothly behind a structural cluster of white mother-of-pearl clouds, creating a highly legibly divided, multi-layered dramatic view that elevates the watch into a kinetic masterpiece.

Manufacture Caliber 1088 L Engine – Certified Self-Winding Moon Phase Core with Openworked Gold Rotor

Ensuring absolute operational precision and kinetic authority is the high-performance mechanical self-winding movement, Caliber 1088 L, calculated, constructed, and hand-decorated entirely within the highest specifications of fine watchmaking. Composed of 164 individual components and 24 jewels, this elite engine operates at a high frequency of 28,800 vibrations per hour (4 Hz) with a movement thickness of 5.03 mm and a 30 mm diameter scale, supplying a trusted 40-hour power autonomy. The caliber integrates an advanced balance-stop mechanism for micro-precision temporal adjustments when synchronizing the sweeping central seconds display. The reverse view sapphire window reveals bridges chiseled with meticulous Côtes de Genève wave patterns, framing a magnificent openworked oscillating weight chiseled from solid gold, shaped into the geometric silhouette of the historic Maltese Cross symbol.
