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.
