SJ Production GR Factory New Product, after 3 years of research, presents the JL Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Mechanical Movement. This replica of the Jaeger-LeCoultre Master Perpetual Calendar series automatic mechanical watch adheres to the philosophy of not counting t.mes
and cost, achieving the full functionality of the complex 868 movement using the imported 9015 movement, consistent with the official version!.1. Perpetual Calendar Function: An invisible button located at the 8 o'clock position allows for year adjustment through the month. The perpetual calendar operates normally, facilitating the operation of the annual calendar module. The year display ranges from 2024 to 2029, simplifying the process of changing the annual calendar module.2. Calendar, Weekday, and Month Discs:. - 1. The calendar disc displays at the 3 o'clock position and can be adjusted forward by pulling the lever to the first position and turning clockwise, while counterclockwise adjustment is not recommended as it may disrupt the monthly display. - 2. The weekday disc is located at the 9 o'clock position and can be adjusted backward using the lever in the second position to set the 24-hour t.mes
. - 3. The month disc is at the 6 o'clock position and can be adjusted via the invisible button at the 8 o'clock position, with a dedicated adjustment lever provided. This enables independent adjustment of all three functions for ease of use while wearing.3. Warning Window Function: Positioned above the central axle on the dial, a fan-shaped window displays white when the year can be manually adjusted and blue during restricted t.mes
periods. It is advised not to adjust the year in the blue area to avoid damaging the movement's lifespan. The 868/1 movement is a complex function movement, not a defect, which is the same for the original.4. Moon Phase Function: Located at the 12 o'clock position, the moon phase window completes a full cycle every 30 days, achieving genuine functionality and a true moon phase display. It can be adjusted backward by pulling the lever to the first position, effectively resolving the issue of the moon phase function not being independently adjustable.Additionally, a user adjustment instruction card will be included to help watch enthusiasts understand the adjustment.mes
thods more clearly.While focusing on functional restoration, the authenticity of the appearance is also a top priority.1. The materials used for the case and bezel are identical to the original, made from high-quality stainless steel. Each component is precisely crafted through CNC machining to restore the original appearance, maintaining the original 39mm size, with the thickness closely matching the original dimensions, achieving an overall thickness of around 10mm while fully implementing all complex functions.2. The dial is restored to the original dimensions, with indices crafted from genuine molds, providing infinite depth and gloss. The dimensions and positions of the indices are strictly QC checked, with the three functional discs designed to be recessed like the original. The moon phase and perpetual calendar windows exhibit a more pronounced three-dimensional effect, with the indices and logo closely following the original design, ensuring a subtly raised appearance. All dial colors have been restored to match the original as closely as possible.3. The watch features a Dauphine hand design, which is iconic for the Jaeger-LeCoultre brand, with a half-sandblasted and half-polished finish. The hour and second hands are slightly bent using micro-press techniques, and the blue hands are heat-treated for a more vivid color.The efforts of the GR Factory are a necessary path to achieving results, striving to replicate this Jaeger-LeCoultre Master Complex Perpetual Calendar watch, allowing watch enthusiasts to not only enjoy it but also to deeply experience the charm of the t.mes
