The ETA caliber 251.232 is a member of ETA’s Thermoline family of SuperQuartz chronograph watch movements. That means it is thermocompensated.
Official documentation has been found dated February 26, 2003, so this movement has been available since at least that long.
Around 2008, the ETA caliber 251.233 was introduced as a direct replacement for the ETA caliber 251.232.
Some of the topics covered in this caliber listing:
The ETA 251.232 was used as the basis for the Breitling calibre 73 (aka B73) until later being switched to the cal. 251.264. If you have a Breitling watch powered by the 251.232, please comment below.
Resetting the Chronograph Hand to Zero:
If your chronograph hand is misaligned (for example, after a battery change), it is easy to get it back to zero (unlike mechaquartz watches).
- Reset the hours counter: Pull the crown out one click to date setting mode, press the top chronograph button (holding longer than one second will make it turn faster) until the hand it lined up where you want it.
- Reset the minutes counter: Same as with the hours counter, while in date setting mode (crown pulled out one click), press the bottom button to advance the hand until it it lined up.
- Reset the chrono seconds hand: Pull the crown out two clicks (time setting mode), then press the top button until the hand is back to zero.
- Reset the 1/10 secs counter: With the crown pulled out two clicks, press the bottom button until the hand is lined up.
Press the crown back in to save the setting.
ETA 521.232 Pros & Cons:
- Extremely accurate
- Easy sequence to reset hands to zero
