Chronograph


Manual and automatic vintage Citizen chronographs.

Citizen had three gorgeous chronograph movements. All three are fly back. One of them is hand winding and two are automatics developed on the same base model. Citizen calibre 5702 has  21 jewels. It beats at 18,000bph. It is the first chronograph and the only hand winding chronograph movement that Citizen produced starting from 1967 up to around 1972.

  1. There is also an automatic one with a two variations: 8100A – has only a minute totalizer.
  2. The 8110A is basically the same as 8100A but has a hour totalizer too.  The date is not quick set but changing by advancing the hour hand.

The first (in the entire world) automatic chronographs are these:  The Zenith El Primero (1969), the Seiko 6139 (1969), the Heuer/Hamilton-Buren/Breitling/Dubois-Depraz caliber 11 (which was a Dubois-Depraz 8510 chronograph module on a Buren 1281 tractor, 1969), the Lemania (1970), the Citizen 8100 fly back (1972), and the Valjoux 7750 (1974).

Both Citizen automatic variations have 23 jewels with hand winding capability. They were produced by Citizen starting from 1972. They are a vertical clutch chronograph (beating at 28.800 bph) with column wheel and fly back function. They have a day and date indicator. The fly back function means that you can reset the chronograph while in motion and it will start again without needing to go the entire process of pressing stop-reset-start. So, one push can do all of this. Of course that if you want to stop it you can go the classic stop-reset way. A particularity for this movement is that when you want to change the day you should pull the crown to second position (for changing the date) and push and release the reset (1 o’clock) button. It is 27 mm wide and 6.9mm high. The column wheel/vertical clutch design of the movement advices to leave the chronograph running for most of the time (this way you can also see the beautiful sweeping central second hand in movement), but from time to time it should be stopped.
