Catalogue description

Dealer description — Oliver & Clarke

Jaeger-LeCoultre is one of the most well-rounded and storied brands in the history of watchmaking. They are not only known for models, but also, at least in the world vintage watches, equally known for their movements — a surprisingly unique accolade that is perhaps unmatched by any other brand. Be there no doubt, the most popular and well-known model from the brand is the properly iconic Reverso, but the brand offers so much more with model families like the Memovox, the Deep-Sea, and a wide range of complicated calendar watches. The collector community certainly knows it, but what is lesser-known are models without names like the fantastic chronograph that we have here. This three-register chronograph dates to circa the 1950s and on top of the stunning yellow gold case, features one of the most respected movements from the era, if not, of all time. Coming in at approximately 35mm in diameter, the case features whimsical 'cows horn' lugs along with a screw-down caseback and 'pump' pushers. Inside, the silver dial with 'concentric' subsidiary registers is very nicely-preserved, with a largely clean surface and excellent text throughout. The applied 'dot' indices and '12' are complimented by a 'dauphine' handset with blued-steel chronograph hands. Powering this piece is the esteemed Valjoux Cal. 72 manually-wound movement, operated by a crown at the 3 o'clock position and 'pump' pushers at the 2 and 4 o'clock positions. Considering JLC is very much know for its in-house movements, this piece is somewhat ironic with its Valjoux movement, which we think, make it all that more interesting. Seemingly lost to time and overshadowed by its contemporaries form other brands, this piece is an absolute gem and theres no saying when another like it may surface on the open market.

Historical context

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

Chronographs and split-seconds watches

A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.

Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.

What to look for

  • Push-pieces on the case band or a single button in the crown (monopusher).
  • Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
  • Column wheel versus cam control visible in the movement.
  • Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).

Dating clues

  • Pocket chronographs with heart cam reset: after 1862.
  • Wrist chronographs: from c. 1910; two-button designs from the 1930s.
  • Automatic chronographs: from 1969.
