Catalogue description

Dealer description — Bulang & Sons

Tudor's second series of chronographs earned the nickname "Monte Carlos" from collectors due to the dial layout, which resembled the gaming tables seen in the casinos of Monaco's famous gaming center. This stunning chronograph features a grey and orange dial in superb condition. The orange remains striking and vibrant, with no spotting on the grey areas, which is often seen on these watches. The case, including the lugs and crown guards, is thick and in great shape all around. The caseback has a fascinating engraving: C. Harris M.N.-U.K. 025557 . We love these little mysteries: Who was this “C. Harris”? Was this from the UK military ? Was this a military-issued watch? And what does the number signify ??! The folded link Oyster bracelet, ref 7836 with 382 endlinks, is in excellent condition with minimal stretch.The manual wind chronograph movement has been fully checked and regulated by our watchmaker.

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.
