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
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.
