More about Jaeger LeCoultre Q3758420 Reverso Grande Calendar SS Silver Dial

This is a stainless steel Jaeger LeCoultre Reverso Grande Calendar, Q3758420. It has an alligator leather strap with a stainless steel double-fold over deployant buckle. The solid five-body case and sapphire crystal display case back are polished with the distinctive rectangular reeded art deco Reverso fixed bezel. The dial is two-tone silver with an inner guilloche rectangle, outer plain reserve, black Arabic numeral hour index markers, blued steel epee hands, and an inner ring with minute markers. There are day of the week and month aperture windows at 12 o'clock, and a combined date and moon phase sub-dial at 6 o'clock. It has a 45-hour power reserve at full wind, and a scratch-resistant sapphire crystal with a push/pull crown. It's water resistant to 30 meters (100 feet), and it measures 29.5mm x 41.6mm, with a thickness of 10.4mm. The dial, case, and movement are all signed.

The Jaeger LeCoultre manual winding Caliber 843 movement is rhodium-plated with fausses cotes embellishment. It's constructed with 19 jewels and a shock absorber mechanism. It includes a straight-line lever escapement, a monometallic balance that's adjusted to 5 positions, and a self-compensating flat balance spring.

In 1931, Cesar de Trey and French designer Renee-Alfred Chauvot created the innovative art deco style Reverso watch, inspired by a challenge by polo players to construct a wristwatch that would resist the abuse of their active sport. In 1984 a completely new Reverso line emerged with enhanced pivots and water resistance.
