Jaeger-LeCoultre

GR Factory 🌐 New Release: After three years of research, we’ve replicated the Jaeger-LeCoultre Master Perpetual Calendar automatic mechanical watch, featuring a fully functional perpetual calendar mechanical movement.Adhering to a philosophy of sparing no expense or time, it achieves full functionality identical to the official 868 movement using an imported 9015 base movement! I. Perpetual Calendar Function: Accessible via the hidden button at 8 o’clock, the calendar year is adjusted through the month dial. The perpetual calendar year operates normally, facilitating the calendar module’s function. The year display (2024-2029) simplifies future perpetual calendar module replacements.2. Date, Day, and Month Displays: – Date display at 3 o’clock: Adjust forward via the first position of the bar-shaped lever (rotate clockwise), backward via the second position (rotate counterclockwise). *Reverse adjustment is not recommended as it may cause the month disc to jump. – Day display at 9 o’clock: Adjust via the second position of the bar-shaped lever (rotate counterclockwise) using the 24-hour format.3. The month display at 6 o’clock can be adjusted via the hidden push-button at 8 o’clock. A dedicated adjustment lever is included for this purpose. This design allows all three functions to be adjusted independently, facilitating operation while wearing the watch.III: Warning Window Function. Located above the central pinion in a fan-shaped aperture, it displays white when the year can be manually adjusted. Blue indicates a restricted adjustment period—avoid changing the year during this phase to prevent compromising the movement’s lifespan. This characteristic applies to the 868/1 complex movement and is not a defect; it mirrors the original design.IV: Moon Phase Dial Function. The moon phase window at 12 o’clock completes a full cycle every 30 days, displaying an authentic moon phase. It can be reversed and adjusted via the first position of the crown extension, effectively resolving the issue of non-independent moon phase adjustment. Additionally, an adjustment instruction card detailing the methods for all the above functions will be included to provide watch enthusiasts with a clearer and simpler understanding. While prioritizing functional restoration, the restoration of appearance is also of paramount importance.1. Case, Bezel, and Case Back: All components utilize the same high-grade stainless steel as the original. Each part is individually CNC-machined to precisely replicate the authentic appearance. Maintaining the original 39mm diameter, the thickness is exceptionally close to the genuine model. Despite incorporating all complex functions, the overall thickness is meticulously controlled, achieving approximately 10mm. 2: Dial Reproduction: Faithfully scaled to the original dimensions, the hour markers are molded as genuine raised indices. Their three-dimensional depth and lustrous finish are meticulously replicated. Both the size and positioning of the indices undergo full QC inspection. The three subdials are recessed, mirroring the original design. The moon phase aperture and perpetual calendar window exhibit pronounced relief effects. The hour markers and logo replicate the original’s slightly raised appearance.All dial colors are meticulously matched to the original. 3: Taffeta hands are employed. These signature Jaeger-LeCoultre taffeta sword-shaped hands feature half-satin-finished, half-polished surfaces. Both hour and second hands undergo micro-bending for enhanced readability. The blued hands are authentic steel-blue, achieving a purer hue. Every effort by GR Factory is an essential step toward achieving the ultimate result: faithfully recreating this Jaeger-LeCoultre Master Complicated Perpetual Calendar watch. This allows enthusiasts to not only appreciate it but also experience its charm firsthand. 🌐
