The new product from GR Factory, after three years of research, features the Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar mechanical movement. The replica of the Jaeger-LeCoultre Master Perpetual Calendar automatic watch has been developed under the principle of not counting t.mes
and cost, achieving the restoration of all functions of the complex 868 movement using the imported 9015 movement, fully consistent with the official version!.1. Perpetual Calendar Function: An invisible button at the 8 o'clock position allows for year adjustment through the month. The perpetual calendar operates normally, facilitating the function module's operation, with the year display ranging from 2024 to 2029, making it easier to replace the perpetual calendar function module.2. Date, Week, and Month Discs: . - The date disc is displayed at the 3 o'clock position and can be adjusted forward by pulling the first gear of the crown, and backward by turning it in reverse. *It is not recommended to adjust backward as it may cause the month display to jump. - The week disc is displayed at the 9 o'clock position and can be adjusted backward through the 24-hour t.mes
by pulling the second gear of the crown. - The month disc is displayed at the 6 o'clock position and can be adjusted by touching the invisible button at the 8 o'clock position. A dedicated adjustment lever will be included for this purpose, allowing for independent adjustments of these three functions, making it convenient for wear.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 in blue, it indicates a restricted t.mes
zone. It is best not to adjust the year during this period to avoid damaging the movement's normal lifespan. Therefore, the 868/1 movement is classified as a complex function movement, which is not a defect but a characteristic of the original.4. Moon Phase Function: Positioned at 12 o'clock, the moon phase window completes a full cycle every 30 days, achieving true functionality and real moon phase display. It can be adjusted backward by pulling the first gear of the crown, effectively solving the issue of the moon phase function not being adjustable independently.Additionally, a card with instructions for adjusting these functions will be provided for users to easily understand the operation.While emphasizing the restoration of functions, the appearance restoration is also a top priority:.1. The material of the case and bezel is the same high-grade steel as the original, with each component precisely crafted through CNC machining to restore the original aesthetic effect. The size remains at the original 39mm, with a thickness that closely matches the original dimensions, achieving an overall thickness of about 10mm while fully realizing the complex functions.2. The dial restoration follows the original dimensions, with the scales being true to the original molds, achieving infinite depth and gloss. The size and position of the markers have passed full QC, with the three functional discs crafted in a manner consistent with the original, featuring more pronounced relief for the moon phase and perpetual calendar windows. The markers and logo closely follow the original, with a slightly raised appearance, and all dial colors are aimed to be as consistent as possible.3. Using the Dauphine hands, which are the signature hands of the Jaeger-LeCoultre brand, these hands are half sandblasted and half polished. The hour and second hands are slightly bent, and the blue steel hands are heat-blued for a more authentic color.The entire effort of GR Factory is a necessary path to achieving results, striving to restore this Jaeger-LeCoultre Master Complex Perpetual Calendar watch as closely as possible, allowing watch enthusiasts to not only appreciate it but also to personally experience the allure of the t.mes
piece.
