Jaeger-LeCoultre Master Ultra Thin Moon with Copper Toned Dial

With the new Master Ultra Thin Moon in grained copper, Jaeger-LeCoultre brings a bolder, warmer tone to one of its most refined and poetic watches. The classic moon phase display, set within a recessed subdial, shimmers against a rich salmon-colored backdrop, adding a contemporary twist to this enduring icon of elegance. Limited to just 800 pieces, this timepiece pairs technical finesse with understated drama, offering a fresh take on the moonphase complication in one of the maison’s slimmest profiles.

The case of the Master Ultra Thin Moon features a polished stainless-steel profile with refined lines and elegant proportions. It measures 39mm in diameter and 9.3mm in height, offering a balanced wrist presence that retains the dress-watch character. The bezel is slim and mirror-polished, complementing the soft curvature of the lugs, which are slightly angled for a comfortable and secure fit.A transparent sapphire crystal caseback reveals the decorated automatic movement within. The exhibition window is framed by a polished rim engraved with technical and model-specific engravings, including the “Master Control 1000 Hours” inscription — a testament to Jaeger-LeCoultre’s rigorous internal testing process.It comes equipped with a knurled setting-crown, embossed with the “JL” logo and sized for smooth manual operation. Discreet corrector pushers are integrated into the case flank, used to adjust the date and moon phase functions independently. A domed sapphire crystal protects the dial, offering distortion-free legibility from multiple angles. Water-resistance can reach up to 50 meters (165 feet), providing protection from splashes and brief contact with water.The dial features a refined copper-toned surface with a matte, grained texture that subtly captures ambient light. This warm hue marks a distinct departure from the silver, blue, and black sunray dials traditionally used in the Master Ultra Thin collection, lending this reference a more contemporary presence. Black-printed minute dots encircle the outer track, providing quiet structure without interrupting the dial’s minimalism.Faceted dauphine-style hands in a half brushed, half polished finish, hover over applied trapezoidal hour markers, extending the case’s elegant restraint to the dial. A recessed, circular sub-dial at 6 o’clock integrates both the moon phase display and a copper-colored date ring. This layered geometry adds depth to the otherwise flat dial, while the dial text and logo remain modestly sized and printed in black to preserve overall clarity.A metallic pointer hand marks the date along the inner ring, while the moon phase occupies the center of the sub-dial. Rendered in silver against a deep blue sky scattered with stars, the moon display rotates as it tracks its lunar cycle. The interplay of warm copper, vivid blue, and polished steel elements gives the dial a classical yet tactile visual appeal.
