As you probably know, the launch of the automatic chronographs is an interesting part of the horological history. Not only because three automatic chronographs were launched the same year, but also because all three are different constructions. I have collected one of each, but now it is time to let them go. Instead of selling them one by one, they come as a small collection.
JDM 6139-6000 Seiko Speed Timer
Some people means that it is the very first automatic chronograph. Regardless, it was the very first to be sold in the open market, in May 1969 Japan. The watch is from the very first batch, manufactured in February 1969, which should make it extremely rare. The movement is 21 jewels unlike the export versions with 17 jewels. Furthermore, it is recognized by its "Proof"-dial and "notched" case.
Original bracelet, JDM
Diameter: circa 40 mm
Movement: 6139A, 21j
The condition is very good. It works as it should and the chronograph resets perfectly.
Zenith El Primero A384
Zenit was the first company to advertise an automatic chronograph on January 10, 1969 (although the development started as early as 1962!). At the time Zenith the presented prototypes of the El Primero. Full-scale production started late 1969. With Serial 707D926 I believe this watch is among the first A384 made. The manufacture of these began in November 1969.
Diameter: 38 mm
The dial has some patina, but it should be possible to clean it if one finds a watchmaker that can do the job. Furthermore, the crystal is slightly damaged at 130 of the tachy. The movement is supposed to be serviced by the last owner, but I haven’t opened the watch and there is no receipt of the service. The watch runs good and resets perfectly.
The Chronocentric group (Heuer, Breitling Hamilton-Buren and Dubois Depraz) competed mainly with Zenith to develop the first automatic chronograph. On March 3, 1969 the group launched the Cal. 11 at several large press conferences. Not too long after the official launce came cal. 11-I with several enhancements, but after further improvements (eg 21600 VPH against former 19800 and enhancement of several other components) they launched cal. 12, the movement in the Dugena. The movement is based on Buren 1281 with micro rotor and the chronograph module 8510 from Dubois Depraz. Despite the construction with a piggy back chronograph, the watch is reasonably slim with its 14 mm height. There is another crown fitted to the watch, but an original crown will be included separately. Nice 70's chronograph with a slightly brown dial (tropical?).
Diameter: 43.25 mm.
Movement: Cal. 12
Unknown service history, but It works flawlessly and resets perfectly.
