GR Factory's new product is a replica of the Jaeger-LeCoultre Master Grand Complication Perpetual Calendar mechanical movement, developed after three years of research. Adhering to the philosophy of not counting time and cost, we have achieved the restoration of all functions of the complex 868 movement using the imported 9015 movement, which is consistent with the official version!.1. Perpetual Calendar Function: The hidden button located at the 8 o'clock position allows for the adjustment of the annual calendar by month. The perpetual calendar operates normally, facilitating the functioning of the annual calendar module, with the year display ranging from 2024 to 2029, making it easier to replace the perpetual calendar module.2. Calendar Disc, Week Disc, and Month Disc Functions: . - The calendar disc displays at the 3 o'clock position and can be adjusted forward by pulling out the first gear and turning it clockwise, or backward by turning it counterclockwise (note: backward adjustment is not recommended as it may cause the moon phase disc to jump). - The week disc is displayed at the 9 o'clock position and can be adjusted backward through a 24-hour time setting by pulling out the second gear. - The month disc is located at the 6 o'clock position and can be adjusted by touching the hidden button at the 8 o'clock position, with a dedicated adjustment lever included for ease of use. This allows for the independent adjustment of all three functions, making it user-friendly.3. Warning Window Function: This feature is located above the central axis of the dial. When displayed in white, it allows for manual year adjustment; when in blue, it indicates a restricted time zone. It is advisable not to adjust the year during this period to avoid damaging the movement's lifespan. This complex 868/1 movement is designed for intricate functionalities, not due to any deficiencies in the movement, which is consistent with the original.4. Moon Phase Disc Function: Situated at the 12 o'clock position, the moon phase window completes a full cycle every 30 days, providing a genuine moon phase display. This can be adjusted backward by pulling out the first gear, effectively solving the issue of the moon phase function not being independently adjustable.Additionally, the adjustment methods for the above functions will come with a user adjustment instruction card to help watch enthusiasts understand the operations more easily.While focusing on functional restoration, the aesthetic replication is also a top priority.1. The materials used for the case and bezel are consistent with the original stainless steel, with each component crafted through precision CNC machining to restore the original appearance. The watch maintains its original 39mm size, and the thickness is kept as close to the original as possible, achieving approximately 10mm while fully realizing all complex functions.2. The restoration of the dial is done according to the original dimensions, with all scales being true to the original mold, offering infinite dimensionality and gloss. The size and position of the markings have undergone strict quality control. The three functional dials are recessed as in the original, with the moon phase window and perpetual calendar window showing a pronounced 3D effect. The scale points and logo are also closely matched to the original, providing a slightly raised visual effect, and all dial colors are restored to match as closely as possible.3. The watch features a Dauphine hand design, which is a signature of the Jaeger-LeCoultre brand, with half sandblasted and half polished finishes. Both the hour and second hands are slightly bent, while the blued steel hands are produced using a burning technique, resulting in a more authentic blue color.The efforts of GR Factory are all part of the journey to achieving this result, aiming to restore the Jaeger-LeCoultre Master Grand Complication Perpetual Calendar watch as closely as possible, allowing enthusiasts to enjoy the charm of this timepiece even more intimately.
