New: Copper-Dial Jaeger-LeCoulte Master Ultra Thin Moon / Date

April 04, 2013

Jaeger-LeCoultre has a reputation for revered watchmaking, all within a single facility in Le Sentier, in the Vallee de Joux. For 2025, La Grande Maison unveils two new Master Ultra Thin timepieces. Both feature a soft, almost terracotta-like shade of copper. The grainy texture also lends the aesthetic a touch of ruggedness. Yet, the playful palette does not diminish the Master Ultra Thins sophistication. It retains its classical layout and brings a tone that warms the soul as the Northern Hemisphere shifts into winter. The new Moon and Date versions share the excellent dial color and texture, and both feature a 39mm stainless steel case. So lets go right to the core of these new JLC watches.The pink gold Reverso Tribute, paired with its Milanese bracelet, has taken center stage this year. Still, JLCs traditional round watches remain relevant. The Jaeger-LeCoultre Master Ultra Thin Moon (ref. Q1368460) and Date (ref. Q1238460) exemplify subtlety. Both dials have finely textured finishes that play with light. In low light, they appear a soft pink, but in direct sunlight, they shift to a vibrant copper. This blend of texture and color elevates the watch beyond a mere dial update.Jaeger-LeCoultre Master Ultra Thin MoonJaeger-LeCoultre is revered in the watchmaking industry. Its calibers stand the test of time, even when undergoing the brand s rigorous 1,000-hour control process. Caliber 925 in the latest Master Ultra Thin Moon is no exception, proudly powering the time and moonphase display. The silver moon disc shines above a deep blue starry background. Surrounding the moonphase aperture is the radial date display, featuring black printing of odd numbers and dots for even dates. The curved section, which indicates the waxing and waning of the Moon, also features extremely fine grooving to vary the texture from the grainy dial. This is a well-balanced use of a complication that avoids overwhelming the Master Ultra Thins minimalism.The razor-sharp dauphine hands are brushed and polished on both sides to enhance legibility. These hands are also perfectly proportioned against the long, trapezoid hour markers. Alongside the 39mm stainless steel case are actuators for the independent setting of the moonphase and date indicators. JLC provides a soft-tipped tool to advance these functions for correct setting. Though if you are caught short, a matchstick tip or cocktail stick works well. My only gripe is that the buttons sit on the sides of the case, which is awkward. Despite innovation from Jaeger-LeCoultres mechanism department, I prefer these functions to be integrated with the crown. Still, caliber 925 provides an impressive 70-hour power reserve and keeps the 9.3mm-thick case looking svelte,Jaeger-LeCoultre Master Ultra Thin DatePrevious iterations of the Master Ultra Thin Date often favor silver, blue, or black dials - all classic choices. But the introduction of the copper dial with a grainy texture truly livens up the model. The date window at 6 oclock features a crisp, black frame that contrasts with the warmer dial base. And just above the date aperture is the text Automatique to remind you of the movements self-winding capability. Caliber 899 is a simple movement, but this 3.3mm-thick mechanism lives up to the Ultra Thin name, owing to the stainless steel cases 7.89mm overall thickness. More so than the Moon model, the Date can own its Ultra Thin moniker. Caliber 899 also features a 70-hour power reserve and utilizes a single external actuator to advance the date.The polished case is as traditional as they come, with sloping case sides that twist at the lugs. An interchangeable brown alligator strap with a stainless steel folding buckle secures the connection. This quick-release system is a welcome modern touch, allowing for tool-free strap changes to match the watch to any occasion. The Jaeger-LeCoultre Master Ultra Thin Date is an elegant timepiece that is both simple in design and exquisitely crafted. For both watches, the calibers receive C?tes de Geneve decoration, meticulously beveling, heat-blued screws, and a 22K gold rotor.
