In the intricate world of luxury watches, the GR Factory’s latest release is making waves. After three years of meticulous research, GR Factory has unveiled their homage to the Jaeger-LeCoultre Master Perpetual Calendar Watch, recreating its legendary movement with an imported 9015 caliber.

Let’s begin with the standout feature: the perpetual calendar function. Using a hidden button at the 8 o’clock position, enthusiasts can adjust the month and year, with the display ranging from 2024 to 2029. The ease of this function means swapping out the calendar module is a breeze for future updates.

Next, the watch’s display is a marvel of engineering with individual calendar, day, and month dials. A careful rotation of the crown adjusts the date — but beware, reverse adjusting is a no-no, as it will interfere with the moon phase function. The day of the week, displayed at 9 o’clock, adjusts through a separate mechanism using the crown. Meanwhile, the month can be tweaked with an 8 o’clock hidden button, conveniently accompanied by a dedicated tool.

A unique safety feature, the warning window, informs users when not to adjust the year (blue means hands-off!). This is crucial for preserving the life of this intricate mechanism.

Not to forget, the moon phase, gracing the 12 o’clock position, completes a full cycle every 30 days. This function, adjusted through the crown, is as accurate as it is visually stunning.

Now, let’s talk aesthetics. GR Factory has gone above and beyond to capture the original’s striking appearance. Crafted with stainless steel, the watch maintains a svelte 39mm size, and a surprisingly slim profile of around 10mm. The dial, a masterpiece in itself, boasts true-to-original markers and a three-dimensional design that mirrors the original Jaeger-LeCoultre aesthetic.

The watch’s hands are the iconic dauphine style, half-matte, and half-polished, with the blued steel variant adding a touch of elegance.

In sum, GR Factory has delivered an impressive tribute to a classic watch, blending functionality with breathtaking design—all ensuring that watch enthusiasts can experience the magic of this piece firsthand.
