Ever wondered what happens when dedication meets horological brilliance? GR Factory has spent three years perfecting a replication of the Jaeger-LeCoultre Master Perpetual Calendar, with its intricate mechanical movement. This isn’t just a watch; it’s a journey into the art of watchmaking.

Underneath its 39mm stainless steel case lies the imported 9015 movement, engineered to emulate the original 868 caliber. The perpetual calendar features allow year adjustments via a hidden button at the 8 o’clock position, displaying years from 2024 to 2029. Why is this crucial, you ask? It simplifies the perpetual calendar module changes.

Now, let’s talk about its exceptional date, day, and month functions. At 3 o’clock, you can adjust the date dial by moving forward or backward. Though tweaking it in reverse might affect the moon phase disc, so it’s best avoided. The day dial at 9 o’clock and the month dial at 6 o’clock can be finely adjusted using the hidden button and manual lever provided.

The warning window, elegantly located above the dial center, signals when it’s safe to adjust the year—white for safe, blue for no-go. This genius design safeguards the watch’s intricate movement, ensuring longevity.

As if this mechanical masterpiece wasn’t enough, the moon phase window at 12 o’clock completes a full cycle every 30 days, and can be adjusted manually, resolving past limitations.

GR Factory has painstakingly ensured that every component mirrors the original in aesthetic appeal. From CNC precision crafting to using the iconic dauphine sword-shaped hands—half sandblasted, half polished—down to the vibrant steel blue needles.

This watch is more than a timepiece; it’s a testament to GR Factory’s commitment to bringing Jaeger-LeCoultre’s horological magic to avid watch enthusiasts.
