{"product_id":"jaeger-lecoultre-memovox-black-e857","title":"Jaeger-LeCoultre - Memovox – Black – E857","description":"\u003cp\u003eThe Jaeger-LeCoultre Memovox holds a distinct place in watchmaking history as one of the first wristwatches to house a mechanical alarm complication, introduced in the 1950s and later adapted into a dedicated dive watch. This reference E857 wears the model's distinctive three-crown case, an architecture built specifically to separate timekeeping, alarm-setting, and the internal elapsed-time bezel into three independent controls. The black dial is laid out for legibility, with an inner rotating disc used to track dive or elapsed time, a signature feature of the Memovox diver's-watch variants.\u003c\/p\u003e\n\u003cp\u003eInside is a manually wound movement built around Jaeger-LeCoultre's mechanical alarm mechanism, which sounds an audible chime by striking a hammer against the caseback at a time set by the user. The movement drives the hours, minutes, and alarm function together, a mechanical feat that made the Memovox a genuinely useful tool for divers tracking time underwater.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Jaeger-LeCoultre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Memovox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e E857\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase (material):\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Manual winding, with mechanical alarm complication\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap\/Bracelet:\u003c\/strong\u003e Leather\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, mechanical alarm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Three-crown case, internal rotating elapsed-time disc\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Investment Watches Inc","offers":[{"title":"Default","offer_id":57349102371142,"sku":"A2379","price":22750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/5559\/3658\/files\/IMG_3738_c9bdefe6-2388-47d4-9fa1-72bf5e3da1fd.png?v=1791496214","url":"https:\/\/www.investmentwatches.com\/products\/jaeger-lecoultre-memovox-black-e857","provider":"Investment Watches Inc","version":"1.0","type":"link"}
