The new product from GR Factory has undergone three years of research into the Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar mechanical movement, resulting in a replica of the Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar automatic watch. Adhering to the philosophy of not counting t.mes
and cost, we have achieved a complete restoration of the complex functions of the 868 movement using the imported 9015 movement, ensuring all functions are consistent with the original!.1. Perpetual calendar function: An invisible button located at the 8 o'clock position allows for month adjustment of the calendar. The perpetual calendar year operates normally, facilitating the operation of the calendar function module. The year display ranges from 2024 to 2029, making it easier to change the perpetual calendar function module.2. Calendar, day, and month function: . 1. The calendar disk shows at the 3 o'clock position and can be adjusted forward by pulling the first gear of the crown or backward by turning it; however, backward adjustment is not recommended as it may disrupt the month display. 2. The day disk shows at the 9 o'clock position and can be adjusted backward by pulling the second gear through a 24-hour cycle. 3. The month disk shows at the 6 o'clock position and can be adjusted by touching the invisible button at the 8 o'clock position, accompanied by a special adjustment lever for easy operation. This allows for independent adjustment of all three functions, making it convenient for wearers.3. Warning window function: Located above the central pin on the dial, a fan-shaped window displays white for manual year adjustments and blue for restricted t.mes
periods. It is advisable not to adjust the year during the blue period to avoid damaging the movement's lifespan. The 868/1 movement is a complex function movement, not a defect, and this is consistent with the original.4. Moon phase function: Positioned at the 12 o'clock location, the moon phase window completes a 30-day cycle, achieving genuine functionality with real moon phases. The adjustment can be made by pulling the first gear backward, effectively solving the issue of not being able to adjust the moon phase function independently.Additionally, a usage instruction card will be included with the adjustment.mes
thods to help watch enthusiasts better understand the features.While focusing on functional restoration, the aesthetic restoration is also a top priority.1. The materials used for the case and bezel are consistent with the original, crafted from high-quality stainless steel. Each component is meticulously made through CNC precision manufacturing, restoring the original appearance and maintaining the 39mm size. The thickness is kept as close to the original as possible, achieving a thickness of about 10mm while enabling all complex functions.2. The dial restoration is based on the original dimensions, with markers made from genuine molds, achieving an unparalleled three-dimensionality and gloss. The dimensions and positions of the markers have undergone strict quality control, with the three functional disks recessed as per the original design. The moon phase window and perpetual calendar window exhibit a more pronounced three-dimensional effect, and the markers and logo closely follow the original, providing a subtly raised appearance. All dial colors have been restored to match as closely as possible.3. The watch features the signature dauphine hands of the Jaeger-LeCoultre brand, with one half sandblasted and the other half polished. Both the hour and second hands utilize a micro-press bending technique, while the blue hands are heat-blued for a more vibrant color.The efforts of GR Factory are all part of the necessary journey to achieve results. We strive to faithfully restore this complex Jaeger-LeCoultre Master Perpetual Calendar watch, allowing enthusiasts to appreciate and experience the charm of the t.mes
piece.
