The Jaeger-LeCoultre Master Control Chronometre Perpetual Calendar Q4178180 breaks conventional wisdom with its ultra-thin steel case, integrated tapered steel bracelet, full HPG dual chronometer certification, perpetual calendar + moon phase function, combining everyday practicality with high-end watchmaking craftsmanship.
With an ultra-thin 39mm and a mere 9.2mm thickness, this watch is suitable for both men and women. It won't feel loose on slender wrists, nor will it feel bulky or restrict clothing from shirt cuffs on larger wrists, making it extremely flattering for Asian wrist sizes. The seamless integration of the case and the three-row stainless steel bracelet is a core aesthetic highlight of this new series. The bezel and lugs feature highly polished chamfered edges, while the case sides and bracelet body utilize a delicate satin brushed finish, creating a soft interplay of light and shadow.
The dial features a sunburst pattern that gradients from the center outwards. In low light, it exudes a restrained and sophisticated feel, while in sunlight, the radiating texture unfolds layer by layer, creating a sophisticated and cool aesthetic that suits all outfits and skin tones. The hands are elegant dauphine-style hands with sharp angles. The calendar layout features a symmetrical and balanced arrangement of four small circular dials, with clear and unobstructed functional areas: the sub-dial displaying the year and month is located at 12 o'clock; the sub-dial at 3 o'clock displays the day of the week; the sub-dial at 9 o'clock displays the date; and the independent moon phase window is located at 6 o'clock, with the moon phase dial inlaid with a hand-hammered gold foil moon, showcasing a subtle yet luxurious detail.
Each sub-dial is adorned with a warm opalescent bezel, its inner surface featuring finely textured circular patterns that contrast with the sunburst finish of the main dial. The signature dauphine hands and trapezoidal applied hour markers exude a clean and sophisticated look, while the minute track allows for precise reading to 1/4 of a second. The entire perpetual calendar mechanism automatically recognizes months of varying lengths and leap years, requiring no manual adjustment before 2100. All calendar functions support single-crown quick-set adjustment, making operation simple and convenient.
The new in-house manufactured 868 automatic perpetual calendar movement is only 4.72mm thick, showcasing Jaeger-LeCoultre's industry-leading ultra-thin technology. It vibrates at 28,800 times per hour, features a silicon escapement, offering strong anti-magnetic properties and stable timekeeping; and boasts a 70-hour power reserve, allowing the watch to be removed on Friday and worn directly on Monday without winding https://www.watchesnearme.co/.
