Catalogue description
Dealer description — Craft & Tailored
This Jaeger-LeCoultre Memovox Ref 3151 is a product of its era, with modest size, wonderful gold filled case, and legible Arabic numerals on the dial. Jaeger-LeCoultre is universally known for their excellent alarm watches and in house movements. The double-crown feature allows for winding and setting the time, as well as setting the alarm. The top crown sets the alarm complication of the timepiece. The alarm is crisp and noticeable which is a key feature of the manual cal. P489/1 movement. This Jaeger-LeCoultre Ref. 3151 is whimsically functional and doubles as excellent dress pieces that suit today's fashion perfectly. This piece would make a great addition to an existing collection and be a great and classic timepiece as a stand-alone piece!

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.
