Blancpain 6654 vs Jaeger-LeCoultre Q3758420: Which Moon Phase Mechanical Watch Is Better?

Which is better, Blancpain 6654 or Jaeger-LeCoultre Q378420?
Blancpain and Jaeger-LeCoultre are both among the top ten watches in the world and have an unshakeable position in the watch industry. Among them, Blancpain is the oldest watch brand in history, while Jaeger-LeCoultre is a century later, so its history is not as rich as that of Blancpain. Mechanical watches with moon phase function have always been the style that watch friends pay attention to. The moon phase function that can show the moon's cloudiness and beauty is also enough to show the value of this watch. Currently on the market can perfectly show the moon phase function is only Jaeger-LeCoultre Master and Blancpain 6654 brand style; Blancpain 6654 and Jaeger-LeCoultre Q3758420 is the popular style of their respective brands. 6654 is more popular, higher recognition. Jaeger-LeCoultre moon phases are relatively understated and introverted. Jaeger-LeCoultre and Blancpain are like Buick and Mercedes-Benz. Blancpain and PP/BG/VC/AP are tied for the top five watches, with Jaeger-LeCoultre ranking second at best. Of course, different grades are not the same, the difference in price is still slightly larger, so which one is better?

The Blancpain 6654 Moonphase is available in nearly a dozen color schemes, with the most popular among watch enthusiasts being the steel case white face, the steel case gray face, and the steel case blue face. The Blancpain 6654 Moonphase with a steel case white face is also the most basic color scheme style and one of the most recognized by watch enthusiasts. The Jaeger-LeCoultre Master Moonphase consists of three main colorways: 1368420 with a white face in a steel case, 1368470 with a black face in a steel case, and 1362520 with a white face in a rose gold case. Of course, the version produced by ZF is the one that is currently capable of realizing the true moon phase function.The ZF Jaeger-LeCoultre Master Moonphase in steel case with white face is the most basic style and the most suitable for formal wear among the three color schemes. The steel-cased black face is the most textured and beautiful model, while the rose gold-cased white face is the most sophisticated and luxurious.

Functionally, both watches have a moon phase function and date. The difference is that Blancpain also has the day of the week and the month. In the history of the full calendar, the quartz storm of the last century brought near devastation to Swiss watchmaking. Blancpain revived the Swiss mechanical watch industry with its inventive full-calendar moon phase. Why? Because full calendar and moon phase are the two main functions in a pocket watch, and for the first time, Blancpain allowed them to exist in a watch with a thickness comparable to that of a quartz watch. Today, for more than 30 years, other brands still follow Blancpain in the planning of the moon phase's dial layout. It can be said that it has always been imitated and has never been surpassed. Therefore, 85% people who buy moon phases will choose Blancpain.
In terms of movements, both Jaeger-LeCoultre and Blancpain are movement suppliers with their own movement factories. The Jaeger-LeCoultre Q378420 uses the Cal 925 movement and the Blancpain 6654 uses the Cal 6654 movement. the 925 is roughly polished and the automatic tourbillon is not like that of the 6654. it is an integral oscillating weight in karat gold. Its oscillating weight consists of two parts. Connected by four rivets, the center is alloy and the edge is K-gold material; on the hairspring, the 925 has an alloy hairspring and the 6654 has a silicone oil silk. It is well known that silicone oil filaments have better antimagnetic properties. The 6654 is well polished. As you can see from the size of the fish scales, it is much more delicate than the Jaeger. Also, the chamfers are mostly rounded and have a polished finish.
In terms of power, the Jaeger-LeCoultre Master is a 43-hour power reserve and the Blancpain 6654 is a 72-hour, which is longer and more practical.
This is actually different as far as dial design is concerned. Personally, I think the Blancpain has more design. The double-ringed three-dimensional dial, K-gold Roman waist indexes, skeletonized willow leaf hands, and serpentine blued steel hands are more recognizable. It's both classic and modern, very good, sophisticated, elegant and durable. The Jaeger-LeCoultre Master's three-dimensional tapered scale with blue seconds hand is also stylish, but a bit dull in comparison.
Having said that, it doesn't have to be better or worse than high or low. Both watches have their advantages. These two watches deserve to be the best mechanical moon phase watches available today. If you like simple and generous design, you should choose ZF Jaeger-LeCoultre Master Moonphase watch. If you like watches with complicated functions and exquisite composition, you should choose OM Blancpain 6654 moon phase watch; if your budget is limited, Jaeger-LeCoultre Master has cheap functions, which is a good choice; if your budget is a little more, think about Blancpain 6654, whether it's better than Jaeger-LeCoultre Master in terms of grade and function or craftsmanship polishing, and buy a piece of one step to the whole world.
