OM has produced the full moon phase multifunctional watch of the Jaeger-LeCoultre Master series. The function and appearance details of this model are exactly the same as the original. Now let's talk about the detailed review of this watch.

The cover-shaped dial has a slight curve when viewed from the side; It was revised many times so that its spirit could rival the original. Case: It was presented flawlessly by being revised many times so that the angle and size of the lines on the four corners of the case surface were the same as the original. The curved fishtail lines of the ears are voluminous and elegant, perfectly conveyed. There is no gap in the middle of the buckle; When viewed from the side, the curve is not interrupted or opened. The curve of the buckle wing is the same as the original, it fits the hand better. It uses a 9015-based movement converted to Jaeger-LeCoultre's own 866/1 caliber; Timekeeping is stable, quality is superior. Dimensions 39 mm x 12 mm. It has been revised and presented flawlessly to capture its spirit. Behind the simplicity lies ultimate complexity.

▲Special note:This original watch we use for comparison is also the watch used to make moulds. Scratches inevitably occur during the mold removal process, but this does not affect our comparative review; You may ignore them.

▲Front face comparison:In this model, the hours and minutes are indicated by the tofu-shaped central hour and minute hands. The most eye-catching part is the brand new date indicator at the far end of the long hand. This hand has a crescent pattern on it and slightly passes over the graduated scale from 1 to 31, located around the outer perimeter of the dial. The OM factory has meticulously processed every detail of the dial.

▲Glass comparison:When we examine the two watches from the same angle in terms of glass, we see that the OM factory uses sapphire crystal glass with extremely good light transmittance. High quality blue coating applied on it; It is clear and bright when viewed from the front, and the reflection effect from the side is exactly the same.

▲Crown comparison: The pushers show the power of the OM Factory. We can understand this from the Blancpain 6654 moon phase model that OM previously released. A great skill is hidden in the tiny button; It is very difficult for a factory without power to achieve such perfection. The logo on the crown is also engraved in full accordance with the proportion and size of the original; buttons and setting functions are exactly the same as the original.

▲Case comparison: The inclination angle and size of the lines on the four corners of the case surface have been kept exactly the same, and have been revised many times and presented perfectly; The curved fishtail lines of the ears are voluminous and elegant, perfectly conveyed. Its flaw is this: the mechanism structure of the annual calendar watch is extremely complex; The total number of parts of the movement is much higher than ordinary three-hand models, reaching 498 parts. Due to technical limitations, the OM version is 1.2 mm thicker than the original.

If you are worried about this thickness but like the model, you can choose the ZF Jaeger-LeCoultre moon phase model. The only difference from OM is that there is no annual calendar; Other functions are basically the same. But to be honest, 1.2mm is barely noticeable to the naked eye.

▲Comparison of the back of the case: The OM factory did not make the slightest negligence behind the case; It is especially evident from the engraving on the back of the case. The depth of engraving is measured and balanced; It never falls short of the original. The inclination angle and size of the lines on the four corners of the case surface have been kept exactly the same, and have been revised many times and presented flawlessly; the curved fishtail lines of the ears are voluminous and elegant, perfectly conveyed

▲Mechanism comparison: The most challenging part of this model is the mechanism. Both the external appearance must be infinitely close to the original and the functions must be the same as the original; That's why OM put great effort into the mechanism part. The original uses its own self-manufactured caliber 866/1; The OM factory uses the imported 9015 movement by converting it into its own 866/1. Timekeeping is stable and reliable. Let's look at the details by enlarging it several times: the screw positions are exactly the same. We all know that it is not easy to make models with transparent soles, but OM factory gave us confidence; Say goodbye to watches whose movements appear fake at a glance.

▲Strap comparison: The original uses an alligator leather strap; The OM factory, on the other hand, uses crocodile pattern printed straps on Italian calfskin. Friends who care about weather can replace it with a crocodile leather strap; crocodile leather is on the market for around 300 per set.

It deserves to be the favorite of official models.
