Jaeger-LeCoultre, also known as Jaeger, is a luxury watch brand that provides some of the most remarkable timepieces in the market. With their longstanding reputation for creating sophisticated and high-quality watches, it's no wonder why Jaeger-LeCoultre is one of the most renowned brands in the industry.

Unlike other watches that require batteries, most Jaeger-LeCoultre watches are powered by mechanical movements. When we say mechanical movements, we refer to watches that have no batteries, but they get their energy from winding the watch or through manual movements by the wrist.
Jaeger-LeCoultre has a unique mastery of hydraulic mechanics, which is why their watches are typically automatic. They rely on the motion of the wearer's wrist to wind the watch automatically, allowing it to keep time continuously. This is why using a Jaeger-LeCoultre watch can be an experience in itself because you get to enjoy the intricate mechanics and craftsmanship that go into making the watch.
However, some of the brand's watches, such as the Reverso Quartz Collection, use batteries to power them. Quartz watches are different from mechanical models because they use a battery instead of winding the watch.
In essence, Jaeger-LeCoultre watches do not necessarily use batteries. Since they boast of intricate hydraulic mechanics, they rely on wrist movement to keep time; therefore, they are automatic.
In conclusion, Jaeger-LeCoultre is a brand associated with the highest quality, exquisite design, and impeccable precision. Each of their watches is unique and carries a legacy of excellence that has come to be expected from the brand. Although some of their watches use batteries, most of them rely on mechanical movements, making them an irresistible purchase for watch enthusiasts who want a timepiece that reflects their love for class and quality.
