Jaeger-LeCoultre, often celebrated for its iconic Reverso timepiece, has garnered a reputation as a true watchmaker’s watchmaker, renowned for its unparalleled mastery of horological movements. While the Reverso remains a standout in the world of timepieces, Jaeger-LeCoultre offers a diverse collection that includes the Master Ultra Thin series, where the art of watchmaking meets graceful design. Among this collection, the Master Ultra Thin Moon stands out with its impressive balance of form and function, featuring a striking blue gradient dial encased in pink gold.

The Master Ultra Thin Moon boasts a 39mm case size, making it versatile for both formal and casual occasions. The polished 18k pink gold case exudes a warm and confident presence with its soft, sweeping curves. The attention to detail is impeccable, from the neither too slight nor too bulky crown to the subtle correction pushers at four and eight o’clock. The watch maintains a harmonious proportion with a slender profile of 9.3mm, and it’s water-resistant up to 50 meters, adding a touch of practicality to its elegance.
The rich midnight blue dial of the Master Ultra Thin Moon is a sight to behold. It transitions from a near-black shade at the edges to a mesmerizing sunray blue at the center. The dial’s layout is well-balanced, with an applied Jaeger-LeCoultre logo and printed wordmark below the twelve o’clock position and a moon phase and calendar display above the six. The level of detailing is precisely what you’d expect from Jaeger-LeCoultre – refined and tasteful, without being overly ostentatious.
The dial features applied elements, from the faceted triangular hour indices to the 46 minute dots that circle the dial. The faceted dauphine handset complements the hour markers elegantly. The combination of the blue and gold elements creates a vibrant and classy aesthetic, evoking images of a muted trumpet’s soulful tunes wafting from a downtown nightclub.

Jaeger-LeCoultre’s movements are renowned for their exquisite craftsmanship, and the automatic Calibre 925 within the Master Ultra Thin Moon lives up to the reputation. With 30 jewels, a beat rate of 28,800vph, and a generous 70 hours of power reserve, it’s a reliable performer. But it’s the decoration that truly sets it apart. Engine turning and Geneva striping adorn the movement, even extending to the skeletonized gold rotor featuring the JLC logo. Blued screws and gold-filled engraving add the finishing touches, all visible through the sapphire caseback.

Completing the ensemble is a lined alligator leather strap in a deep blue hue, complementing the dial’s tones. Measuring 21mm between the lugs, it’s a unique size that maintains proportion with the case’s dimensions. An 18k pink gold pin buckle seals the deal, adding that final touch of sophistication.
The Jaeger-LeCoultre Master Ultra Thin Moon is a horological masterpiece that effortlessly combines elegance, expert craftsmanship, and a dash of uniqueness. With a price tag of A$37,000 or US$23,000, it’s an investment in both style and substance.
