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 one of 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.

The case itself remains very well preserved and is believed to remain unpolished showing crisp factory lines and finishing with only minimal signs of previous use. The "Pepsi" Tachymeter bezel is in excellent condition and remains bright in coloration with no major signs of previous use. The case retains its original button crown and pump-pushers. The case back is believed to remain unpolished as well as it retains its original concentrate brushing with its factory markings remains crisp and deep. The watch will come supplied on a 2pc handmade leather strap. DIAL & HANDS The blue metallic “Water 70m Resist” dial is in lovely vintage condition, showing normal signs of age throughout and some light marks in the 6 o'clock sub-dial. The rotating inner ring has faded to a beautiful powder blue coloration while its silver printing remains visible, the ring does show light signs of age which is common, and it retains its lume triangle at the 12 o'clock position. The lume plots all remain fully intact when inspected under U.V. light and exhibit some dark spots which is normal. The original hands match the dial perfectly and show no degradation under U.V. light inspection. ACCESSORIES None. The watch is functioning and keeping time perfectly, previous service history is unknown.
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.
