Catalogue description

Dealer description — Bulang & Sons

The first and most famous Tudor chrono… This year marks 50 years of the Tudor chronograph, you can read our story here ! The first watch and the one that kicked it all off was the 700 series, known by collectors as the Home Plate due to the hour markers that look like the home plate on a baseball field. We are offering the reference 7031 with black plastic tachymeter bezel. The bezels on these watches can often be damaged but this example is really really great. The dial is in fantastic condition with no corrosion or bubbling and the hour markers have taken on a nice, creamy patina. The case, including lugs and crown guards is in excellent condition. The folded link Oyster bracelet reference 7836 is in good condition with minimal stretch, has a clasp stamped ‘1 71’ and is fitted with ref 282 endlinks. The watch has been fully serviced 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.
