Catalogue description

Dealer description — Craft & Tailored

Tudor has a long history of well made, purpose-built chronographs. The most sought-after and interesting is that of the "Monte Carlo". Boasting a 3 color dial of generally vibrant colors. The "Monte Carlo" is at its core, a high visibility racing chronograph. First produced in 1970 and featured in 3 references and bezel styles; plastic bezel, stainless steel bezel, and a rotating bezel variant. This specific Tudor "Monte Carlo" chronograph Reference 7159/0 is the second iteration of the Tudor chronograph. Featuring a newer Valjoux cal. 234 movement allowing a date function at the 6 o'clock position. The dial was updated to block style markers and baton hands for a more conservative presence whilst remaining equally visible. This watch is loved by collectors as one of the more creative and design-oriented vintage chronographs ever produced. In result, we are seeing less and less on the open market as beloved collectors are keeping them and holding onto them creating a substantial demand increased in recent years.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
