积家的自产机芯能挂一面墙。积家的前身是Antoine LeCoultre成立的LECOULTRE BORGEAUD & CIE，从1860年到1900年就生产了350种不同的机芯，其中超过一半是复杂功能机芯。1903年，Antoine LeCoultre的孙子Jacques-David LeCoultre和来自巴黎的Edmond Jaeger合作，推出了LeCoultre 145超薄机芯、Reverso等经典款式。1931年，两家品牌正式合并，JAEGER-LECOULTRE诞生。
 
Even before Richemont bought Jaeger-LeCoultre, Jaeger-LeCoultre had supplied movements to several Manufactures, including Patek Philippe, Audemars Piguet, Vacheron Constantin and A. Lange & Söhne. After joining Richemont, he took on the role of R&D center, designing the Cal.8000 base calibre for Cartier and assisting Panerai in the development of the in-house movement.
 
Jaeger-LeCoultre itself is also a benchmark when it comes to complications, with the 2006 Reverso 3-sided watch with a total of 18 complications, the 2007 Duometre with independent movement and complications, the Extreme Lab with six patents, and the 2009 Grand Sonnerie that directly challenged the ultimate complication. Each time Jaeger-LeCoultre launches a "big watch", it has a year's worth of topics.
 
In addition to complications, Jaeger-LeCoultre is also the owner of the title of "the world's thinnest mechanical watch", with the 3.6mm Master Ultra Thin Squelette being 0.05mm thinner than Piaget's P900 and priced at CHF 58,000. Although this "thinnest" is a reflection of strength, the 4.05mm Jubilée is more recommended, the design is classic and much more low-key, and the cost performance is higher, the platinum limited edition public price is about 120,000 yuan, and the price of red gold 1907 is only 105,000 yuan.
 
It's hard not to mention Reverso, a collection that was originally born as a men's watch and has since grown to a wider range. Last year marked the collection's 85th anniversary, and the brand launched the Reverso One collection exclusively for women. Whether it is a men's or women's model, the Reverso has captured the hearts of many people with its reversible design. The strap of the Reverso One uses a cowhide rope bracelet, which is its biggest feature, and the width of 16.3mm with a slender cowhide rope can better reflect the elegance of women. Another benefit of using a quartz movement is that the price is kept as low as possible without sacrificing reliability, and the official price of the Reverso One is only 57,000 yuan, which is a very good price.
 
In addition to Reverso, a "date series" can also be recommended for ladies. In just four or five years, the "Dating Collection" has become the most important collection of Jaeger-LeCoultre, accounting for half of Jaeger-LeCoultre's sales, and the new models each year have more options than other collections, including materials, straps, and dials, to cater to the tastes of more female customers. It is no exaggeration to say that every lady can find her favorite style in the "Dating Collection". The entry-level model of the "Dating Series" is priced at around 70,000 yuan, and there are more options in the price range of 100,000 to 150,000 yuan, and it is also the main sales style.
