Jaeger-LeCoultre. Remarkably Rare and Extremely Fine Chronograph in Yellow Gold, With Hinged Case-Back, Black Dial, Retailed by Cartier, With Cartier Reference Numbers Engraved Under the Upper Pusher Model: Chronograph Case Material: Yellow Gold Bracelet Material: Leather Strap Year: 1940s Movement: Manual Caliber: 285 Case N°: 587382 Dimensions: 35 mm Signed: Dial, Case and Movement Not all companies in the watchmaking field have been able to stand the test of time quite like Jaeger LeCoultre, also known as the “watchmaker’s watchmaker.” In the early 1900s, Cartier’s watch supplier Edmond Jaeger sought out LeCoultre’s help in creating the world’s thinnest watches. The collaboration resulted in the creation of Cartier’s earliest Tank and Santos watches, all housed with LeCoultre movements. The present watch is a highly interesting and very peculiar chronograph wristwatch. Signed LeCoultre, exactly like the movement, the yellow-gold case measuring 35 mm has a hinged back that reminds me that of the pocket watches and has been preserved in nice conditions. The extremely gorgeous black gilt dial is a mixture of complexity and beauty. On the dark background both the outer pulsation scale and the inner circle tachymeter one stand out, together with the big Breguet gilt numerals and subsidiary dials. Considering the previously mentioned collaboration between LeCoultre and Cartier, doesn’t surprise that almost in the middle of the dial is printed the name of the French jeweler. Already rare for this peculiarity, the most meticulous passionate will surely note and appreciate the four digits 9309 on the back of the upper chronograph pusher, which are the identifier number of Cartier. A small treasure chest of rarity, this watch is without a doubt the perfect piece for the true connoisseur of vintage watches. Estimate € 30000 - 60000
