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.

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.
