Jaeger-LeCoultre

GR Factory’s new release, developed after three years of research on the Jaeger-LeCoultre Master Complements Perpetual Calendar mechanical movement, replicates the Jaeger-LeCoultre Master Perpetual Calendar Automatic mechanical watch.Adhering to a philosophy of sparing no expense or effort, it employs an imported 9015 movement to replicate all functions of the integrated 868 movement, achieving perfect alignment with the official model! I. Perpetual Calendar Function: Accessible via the hidden button at the 8 o’clock position, the calendar year can be adjusted through the month. The perpetual calendar year operates normally, facilitating the functioning of the calendar module. The year display ranges from 2024 to 2029, simplifying the replacement of the perpetual calendar module.2. Date, Day, and Month Displays: – Date display at 3 o’clock: Adjust forward via the first position of the bar-shaped lever (clockwise) or backward (counterclockwise). *Reverse adjustment is not recommended as it may cause the month disc to jump. – Day display at 9 o’clock: Adjust backward via the second position of the bar-shaped lever (counterclockwise) using the 24-hour time format.3. The month display at 6 o’clock can be adjusted via the hidden pushbutton at 8 o’clock. A dedicated adjustment lever is included for this purpose. This design allows all three functions to be adjusted independently, facilitating operation while wearing the watch.III: Warning Window Function. Located above the central pinion in a fan-shaped aperture, it displays white when the year can be manually adjusted. Blue indicates a restricted adjustment period—avoid changing the year during this phase to prevent compromising the movement’s lifespan. This applies to the 868/1 movement, a complex mechanism, and is not a defect—the original design operates similarly.IV: Moon Phase Disc Function. The moon phase window at 12 o’clock completes a full cycle every 30 days, displaying an authentic moon phase. It can be reversed and adjusted via the first position of the barrel extension, effectively resolving the issue of non-independent moon phase adjustment. Additionally, an adjustment instruction card will be included for all the above functions, enabling watch enthusiasts to understand them more simply and clearly. While prioritizing functional restoration, appearance restoration is also of paramount importance.1. Case, Bezel, and Case Back: All components utilize the same high-grade stainless steel as the original. Each part is individually CNC-machined to precisely replicate the authentic appearance. Maintaining the original 39mm diameter, the thickness is exceptionally close to the genuine model. Despite incorporating all complex functions, the overall thickness is meticulously controlled, achieving approximately 10mm. 2: Dial Reproduction: Faithfully scaled to the original dimensions, the hour markers are molded as genuine raised indices. Their dimensionality and luster are meticulously replicated, with precise QC on both size and positioning. The three subdials are recessed, mirroring the original design. The moon phase and perpetual calendar windows exhibit pronounced three-dimensional relief. Hour markers and logos replicate the original’s slightly raised appearance.All dial colors are meticulously matched to the original. 3: Taffeta hands are employed. These signature Jaeger-LeCoultre taffeta sword-shaped hands feature half-satin and half-polished finishes. Both hour and second hands undergo a micro-bending process, while the blued hands are treated with a steel-blue finish for a purer blue hue. Every effort by GR Factory is an essential step toward achieving the ultimate result: faithfully recreating this Jaeger-LeCoultre Master Complicated Perpetual Calendar watch. This allows enthusiasts not only to cherish it but also to intimately experience the watch’s allure.
