Catalogue description

Dealer description — Craft & Tailored

The first automatic chronograph is a heavily disputed claim as multiple watch companies debuted what they claimed as "the first" automatic chronograph in the year 1969. However, The Seiko 6139-6000 was the first automatic chronograph that was available for purchase in May of 1969 exclusively to the Japanese market. Not only was the ref. 6139 the first production automatic chronograph but the watch also features a quickset day and date complication that is operated through the pushing of the button style crown. This rare "notch-case" model is in remarkable condition, with its deep blue dial, rich "Pepsi" bezel, and original stainless steel bracelet. You'd never know it's over 50 years old just by looking at it – so, here's to another 50 with one of the coolest watches Seiko has ever made. (Col.

The name refers to the subtle notch in the case that slightly exposes the crown. It was replaced with a more flush design in 1970. The case itself remains very well preserved with no notable evidence of previous polishing present, showing crisp original factory lines and finishing with only gentle signs of use. The "Pepsi" tachymeter bezel is in excellent condition and remains bright in coloration with no major signs of age or wear. The case retains its original button crown and pump pushers. The case back retains its original concentric brushing with its factory markings remaining crisp and deep. The watch will come supplied on its original Seiko "H-Link" stainless steel bracelet. DIAL & HANDS The deep blue "Water 70m Resist" dial is in incredible condition, showing true depth of color and no notable elements of age. The rotating inner ring has faded to a grey-blue coloration while its silver printing remains clearly visible. The lume plots are all a striking white color and remain fully intact when inspected under UV light. The original hands match the dial perfectly and exhibit no degradation under UV light inspection. ACCESSORIES The watch comes with its original inner and outer box, Seiko guarantee booklet that remains unfilled out, the Seiko instruction booklet, and the rare Seiko datewheel hangtag. The watch is keeping time, but the service history is unknown. A movement service can be provided upon request.

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.
