Catalogue description

Dealer description — Bulang & Sons

The Rare European market tropical alarming dive watch… We are pleased to offer an incredibly rare European version of the JLC Deepsea Alarm – the diver’s Memovox ! The watches were only produced for a few year years between 1959 and 1962 and the watch used the alarm function to tell the diver he needed to return to the surface.Only Around 1000 of these watches are been produced ; around 800 pieces for the American market ( with an all different dial ) and around 200 for the European market , so this is truely a rare beast !! The word ‘Memovox’ was invented by Jaeger Le Coultre and is actually an amalgamation of two Latin words. Memor, which means remembering and Vox, which means voice. This watch is housed in a large size waterproof compressor case with two crowns – one to wind and set the watch and the other to set and wind the alarm. As with the whole watch, the dial is in beautiful original condition, with a dark brown outer rim and black inner rotating disc. The bezel is all original and in really good condition too. The whole watch has taken on a lovely warm patina and we love the big impact this big watch has- a really purpose build dive tool vibe ! The watch comes on our Nautic basket weave black rubber strap that resembles the vintage Tropic strap on which these watches were often worn. In 2011 Jlc made a re-issue of this watch – which was slightly bigger and ofcourse an updated movement, but in our opinion the vintage version has more charm ! The watch has been fully serviced by our watchmaker. Specifications - Reference E857 - Lecoultre k815 automatic movement - Dates to the early 1960s - T39mm steel compressor case - Black dial with dark brown outer rim - Hammer’ alarm system - Movement serial 1746xxx - Nautic black rubber strap - Fully serviced by our watchmaker - Includes a handmade single leather watch pouch

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide

Wristwatches

Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.

After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.

What to look for

  • The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
  • The calibre: its maker and number are often stamped under the dial or on the bridge.
  • Originality of dial, hands and crown — refinished ('redial') dials are common.
  • Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.

Dating clues

  • Wire-lug cases: before c. 1925.
  • Water-resistant screw-down cases: from 1926.
  • Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
