Catalogue description

Dealer description — Craft & Tailored

Antoine LeCoultre created the LeCoultre brand in 1833, originally creating movement blanks—or unfinished movements—for some of Switzerland's most prestigious watchmaking houses, including Vacheron Constantin, Audemars Piguet, and Patek Philippe. In 1937, LeCoultre merged with Jaeger to form Jaeger-LeCoultre and went on to become the brand we know and love today (though until the 1980s Jaeger-LeCoultre reserved the name “LeCoultre” only on their watches destined for the United States). The brand has crafted myriad iconic and timeless watches, but one of the more interesting pieces is the Powermatic—the first wristwatch to offer a power reserve indicator, with 40 hours of power reserve when fully wound. This piece is a fantastic, clean example of this iconic watch, featuring a 14k gold case with matching gilt hands and hour markers, plus the power meter at 12 o'clock which adds a little mystery to watch for the uninitiated. And the fact that it comes with its original box and papers makes it even sweeter.

The power meter sitting at 12 o'clock is white when the watch is fully wound, then switches to red as the movement gets low on power. The gilt hour markers, including an Arabic numeral at 12 o'clock, are all flawless, as are the matching sword-style hands. ACCESSORIES

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

Automatic (self-winding) watches

Self-winding watches use the wearer's motion to wind the mainspring. Abraham-Louis Perrelet and Breguet made 'perpétuelle' pocket watches with oscillating weights in the late eighteenth century, but the principle only became practical in the wristwatch. John Harwood patented a bumper automatic in 1923; Rolex's Perpetual rotor (1931) winding in one direction, and later bidirectional rotors (Eterna, Felsa Bidynator), established the modern form. Micro-rotors (Universal Genève, Buren) and peripheral rotors made automatic watches thinner.

What to look for

  • A semicircular rotor turning 360° over the movement, or a 'bumper' weight that rebounds between springs.
  • 'Automatic', 'Perpetual' or 'Self-winding' on the dial.
  • A sealed screw-back case, since automatic watches are wound less often by the crown.

Dating clues

  • Bumper automatics: 1923–c. 1955.
  • Full rotors: from 1931 (Rolex); widespread after c. 1950.
  • Micro-rotors: from 1954–1958.
