The ETA caliber 251.262 is a 27 jewels quartz chronograph movement. It is part of the Flatline line of movements. This caliber was introduced in 1988. This movement is no longer in production and has been discontinued. Despite some sites incorrectly stating this is a thermocompensated movement, it is not (ETA 251.264 and 251.233 are Thermoline movements).

Central Chronograph Minutes

Caliber 251.262 is favored by many chronograph enthusiasts because behind the central chronograph second hand is a central chronograph minute hand that counts up to 60 minutes. The subdial at 2:00 calculates 1/10 second when the chronograph is stopped.

As of this post, the caliber 251.262 has been discontinued. Caliber 251.264 is the updated version of the caliber 251.262. The 251.264 is thermocompensated and the 251.262 is not. You maybe able to use the 251.264 as a replacement for your broken 251.262 movement. If you do this, please tell us about the conversion in the comments below.

Resetting the Chronograph Hand to Zero

If your chronograph hands are not lining up after a battery change, use the following steps to reset them back to 12:00 or zero:

  • For the 12 hour counter at 10:00, pull the crown out one click to hour hand/date setting position and press the top chronograph pusher. Each push will advance the hand forward one click, you can hold the pusher in to advance the hand faster. When the hand is lined up, press the crown back in.
  • For the 60 minute central chrono hand, similar to the steps for the 12 hour counter above, pull the crown out to hour hand/date setting position and use the bottom chronograph pusher to advance the hand until it is lined up. Push the crown back in.
  • For the 60 seconds central chronograph hand, pull the crown out 2 clicks to the time setting position. Use the top chronograph pusher to advance the hand until it is lined and push the crown in.
  • To reset the 1/10 second subdial hand at 2:00, pull the crown out 2 clicks to the time setting mode and use the bottom chronograph pusher to advance the hand until it is lined up. Push the crown back in.

The small seconds subdial at 6:00 does not need reset because it is continuously running.

This is the same movement as the one in my Tissot PR 200 chronometer. It’s been very reliable – still keeping perfect time even though I bought it in 1992.

Isn’t there a difference between versions of this movement? I was under the impression that the location of the date window on your watch was the determining factor on the variations of the ETA 251.262.

251.262 can also be found in tag heuer 2000 series chronographs (like mine). It is precise and sturdy. Always check the crown because it has the tendency to hollow at the point it touches the skin (because of the sweat) and as a result water gets into the watch. It destroyed one of the 2 red coils which control the chronograph but I got it from ebay.
