Catalogue description

Dealer description — Craft & Tailored

The Eberhard & Co. brand is firmly rooted in Swiss watchmaking history and was once the largest Swiss watch manufacturer in the early 1900s. The founder George-Emile Eberhard founded the company at the young age of 22 years old in La Chaux-de-Fonds, Switzerland. Though Eberhard & Co. greatly influenced the rise of the Swiss watchmaking history, the brand is most well-known for its post-war wristwatches, such as the elegant Extra-Fort chronograph and the Scafograph diving sports watch. SPECS Stock # EBHEF14801 Brand Eberhard & Co. Style Extra-Fort Model 14801 Serial 4XX Size Men's Material 18K Yellow Gold Dial White Millimeters 36 Bracelet 2pc Handmade Leather Strap CASE & BRACELET The 18k yellow gold case on this Eberhard Extra-Fort retains every factory angle and line in sharp, unaltered, and unpolished condition. The original case geometry remaining intact is seldom seen on early Extra-Fort watches, especially in yellow gold, due to most examples being polished at some point in the past. The Eberhard signed crown and square or flat pushers are original to the watch and exhibit a sharpness rarely seen. The case back retains deep and crisp factory engravings. DIAL & HANDS The multicolored white dial features a blue tachymeter scale and proud red 50-marker that give the watch personality without compromising its sophistication. The condition of the dial is exceptional and original, showing a charming yet light patina from age. The sharp and elegant dauphine hands also remain in original condition showing light and even patina much like the dial. ACCESSORIES None. The watch is in perfect working condition, previous service history is unknown.

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.
