Historical context
Mechanical Renaissance (1990 – 2010)
Mechanical watches return as cultural objects; independent watchmaking flourishes.
Mechanical watches returned as cultural and luxury objects. Complications, tourbillons and new materials proliferated; independent watchmakers such as George Daniels, F.P. Journe and Philippe Dufour revived artisanal watchmaking; collecting vintage watches became a major field.

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.
