About this reference
The Jaeger-LeCoultre Deep Sea Alarm reference E857 was produced between 1959 and 1962, with a total production run of approximately 1,061 units. It is the first diving watch to incorporate an alarm function, utilizing the caliber 815 bumper automatic movement. Collectors distinguish between two primary dial variations: the "LeCoultre" signed version intended for the American market and the "Jaeger-LeCoultre" version for the European market. The 39.5mm stainless steel case features a non-rotating bezel and a 100-meter depth rating. Due to its limited production and historical significance as a pioneering alarm diver, the E857 currently commands prices between $35,000 and $60,000 on the secondary market, depending on condition and dial originality. A notable auction result occurred in 2021 when a well-preserved European-dial example sold for over $70,000. Many surviving examples exhibit significant bezel wear, making original, intact inserts a primary value driver.
