Catalogue description

Dealer description — Analog/Shift

Most are no doubt familiar with Jaeger-LeCoultre via the famed Reverso. But that’s not La Grand Maison’s entire story. The dynamic Swiss watchmaking powerhouse is responsible for myriad iconic designs, from — yes — reversible dress watches, to alarm-equipped dive watches, to complicated masterpieces, and more. Indeed, the storied company has one of the most diverse offerings in fine watchmaking. The particular Jaeger-LeCoultre we have here couldn’t be farther, for example, from the elegant simplicity of the Reverso. A Reference 159.T.C7 Master Compressor Chrono GMT Navy SEALs Limited Edition — (say that three times fast) — it’s part of a special run of just 500 pieces made as a collaboration with the U.S. Navy SEALs. Dating from circa the 2010s, it’s housed in a chunky 46mm titanium case with a sapphire crystal, a signed and locking crown, locking pushers, and a titanium and ceramic unidirectional dive bezel. It features a luminous multi-textured black dial with recessed sub registers, a matching white handset with a skeletonized GMT hand, and a chronograph display with GMT functionality. Powered by the in-house, automatic Jaeger-LeCoultre Calibre J757 movement with 65 hours of power reserve, it comes paired to a black rubber coated titanium bracelet with a signed double push-button deployant clasp. Measuring 18mm tall and packed with functionality, this is no joke of a dive watch; indeed, given its dive and GMT features, it makes a perfect daily driver — provided one has the wrist for it! In excellent condition, this example even includes its factory goodies. Extremely limited and rare, t his is modern watchmaking in its most badass manifestation.

Historical context

Contemporary Horology (2010 – Present)

Silicon components, connected watches, optical-lattice research clocks and a thriving independent scene.

Smartwatches became the world's best-selling watches, while mechanical watchmaking focuses on craft, innovation (silicon components, new escapements) and independent makers.

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.
