After three years of research, the GR Factory has developed a new product featuring the Jaeger-LeCoultre Master full-function perpetual calendar mechanical movement. This replica of the Jaeger-LeCoultre Master Perpetual Calendar Automatic Watch is committed to restoring all the complex functions of the original 868 movement using the imported 9015 movement, without regard to t.mes
and cost, ensuring that all functionalities are consistent with the official specifications.1. Perpetual Calendar Function: An invisible button at the 8 o'clock position allows for adjusting the annual calendar by month. The perpetual calendar operates normally, displaying years from 2024 to 2029, making it easier to replace the perpetual calendar module.2. Date, Day, and Month Disks: . - The date disk is displayed at the 3 o'clock position and can be adjusted forward by pulling the first position of the crown and turning clockwise, or backward by turning counterclockwise. *It is not recommended to adjust backward as it may cause the month disk to skip. - The day disk is displayed at the 9 o'clock position and can be adjusted backward through the second position of the crown using a 24-hour t.mes
adjustment. - The month disk is displayed at the 6 o'clock position and can be adjusted via the invisible button at the 8 o'clock position. A dedicated adjustment lever will be provided to facilitate the adjustment of all three functions independently, making it easy to operate while wearing the watch.3. Warning Window Function: Located above the central axis of the dial, there is a fan-shaped window. When displayed in white, the year can be manually adjusted; when displayed in blue, it indicates a restricted t.mes
zone where it is advisable not to adjust the year to avoid damaging the movement's lifespan. Thus, the 868/1 movement is a complex functional movement and not a defect, as is the case with the original.4. Moon Phase Disk Function: Positioned at 12 o'clock, the moon phase window completes a full cycle every 30 days, achieving true functionality with an accurate moon phase. This can be adjusted backward by pulling the first position of the crown, effectively solving the issue of independent moon phase adjustment. Instructions for adjusting these functions will be included to help watch enthusiasts understand them more clearly.In addition to restoring functionality, the appearance is equally important:.1. Case Material: The case and bezel are made from the same high-quality stainless steel as the original. Each component is precisely crafted using CNC technology to replicate the original appearance, maintaining the original 39mm size, with thickness closely matching the original dimensions. The overall thickness is controlled as much as possible, achieving approximately 10mm.2. Dial Restoration: The dial is restored to the original dimensions, with all markers being genuine molds, ensuring depth and gloss are faithfully replicated. The sizes and positions of the markers are subject to strict quality control. The three functional disks are designed to be recessed, with the moon phase and perpetual calendar windows having a pronounced three-dimensional feel. The marker points and logo are also closely matched to the original version, presenting a subtle convex appearance, with all dial colors closely replicated.3. Using Dauphine Hands: The Dauphine sword-shaped hands are a signature of Jaeger-LeCoultre, featuring one half sandblasted and the other half polished. Both the hour and second hands are slightly bent, while the blue hands are heat-treated for a more vibrant blue hue.The efforts of the GR Factory are all part of the journey to achieve results, striving to faithfully replicate this Jaeger-LeCoultre Master Complex Perpetual Calendar Watch, allowing watch enthusiasts to not only appreciate the design but also experience the charm of the t.mes
piece more intimately.
