SJ Production .GR Factory presents a new product developed over three years: the Jaeger-LeCoultre JL LP2 Master Perpetual Calendar mechanical movement. This replica of the Jaeger-LeCoultre Master Perpetual Calendar automatic mechanical watch adheres to the philosophy of disregarding t.mes
and cost, achieving the restoration of all functions of the complex 868 movement using the imported 9015 movement, consistent with the official model! .Master Series .1. Perpetual calendar function: An invisible button located at the 8 o'clock position allows for month adjustment of the calendar. The perpetual calendar runs normally, facilitating the operation of the annual calendar module. The year display ranges from 2024 to 2029, making it easier to change the perpetual calendar module.2. Calendar, week, and month discs: . 1. The calendar disc at the 3 o'clock position shows the date and can be adjusted forward by turning the first gear pulled from the stem and backward by reversing it. *Backward adjustment is not recommended as it may cause the month wheel to skip. 2. The week disc at the 9 o'clock position can be adjusted in reverse through the second gear pulled from the stem by using a 24-hour t.mes
setting. 3. The month disc at the 6 o'clock position can be adjusted via the invisible button at the 8 o'clock position. A dedicated adjustment lever will be provided to facilitate independent adjustments of these three functions for ease of use while wearing the watch.3. Warning window function: Located above the central axis of the dial, this fan-shaped window indicates the year. When displayed in white, the year can be manually adjusted; when displayed in blue, it indicates a restricted t.mes
period. It is advisable not to adjust the year during this t.mes
to avoid damaging the movement's lifespan. The 868/1 movement is a complex function movement, consistent with the original.4. Moon phase disc function: Located at the 12 o'clock position, the moon phase window completes a full cycle every 30 days, achieving true functionality with an accurate moon phase. It can be adjusted in reverse using the first gear pulled from the stem, effectively resolving the issue of the moon phase function not being independently adjustable.Additionally, the adjustment.mes
thods for the above functions will come with an instructional adjustment card to help watch enthusiasts easily understand the operation.While focusing on functional restoration, the appearance restoration is equally important: .1. The case and bezel are made of the same high-quality stainless steel as the original. Each component is meticulously crafted using CNC technology to restore the original aesthetic. The size remains at the original 39mm, with a thickness closely matching that of the original, achieving an overall thickness of around 10mm while ensuring all complex functions are fully realized.2. Dial restoration: The dimensions are restored to original specifications, with indices crafted from genuine molds, providing unmatched three-dimensionality and gloss. The sizes and positions of the indices have undergone full quality control, with the three functional discs recessed as per the authentic model. The moon phase and perpetual calendar windows have a more pronounced three-dimensional feel, and the indices and logo are faithfully reproduced, offering a subtle raised appearance. All dial colors have been restored as closely as possible to the original.3. Using the signature Dauphine hands, which are half sandblasted and half polished, the hour and second hands feature a slight bend technique, while the blue hands are heat-treated for a more vivid blue.The GR Factory's commitment to restoring this Jaeger-LeCoultre Master Perpetual Calendar watch allows enthusiasts to not only appreciate its beauty but also to truly experience the charm of the t.mes
piece.S1 is a refined recommendation for a men's multifunctional mechanical watch.
