The ETA 2892-A2 is based on the original ETA caliber 2892 automatic watch movement.

Accuracy

Accuracy of the ETA caliber 2892-A2 can range from as much as +/-20 seconds per day to just +/-5 seconds/day. The accuracy that your watch experiences depends on the grade that the watch manufacturer chose to power their watches.

Grades

Similar to other ETA movements, there are 3 grades of production quality.

  • Elaborated Grade – Adjusted to four positions / average accuracy of +/-5 sec/day to +/-20 sec/day.
  • Top Grade – Adjusted to five positions / average accuracy of +/-4 sec/day to +/-15 sec/day.
  • Chronometer (COSC) Grade – Adjusted to five positions / average accuracy of -4/+6 sec/day.

From Wikipedia:

The key components which differ at the line of demarcation between Elaborated and Top are the pallet stones, balance wheel & hairspring, and the regulator mechanism. The degree of decoration on the movement’s parts also increases with the grade. –Source

Are you also going to post ETA 2897 ? or is it the same movement as the 2892 only with the Power Reserve complication?

My Breitling Chrono Cockpit houses a Breitling 30 calibre that I believe is based on the ETA 2892-A2 movement. My Omega De Ville has a 1120 based off the ETA 2892-A2 also. Am I correct?

I own a Steinhart pilot with this movement, Elaboré grade. For months now i did not have to adjust a time as it is dead on within a 0.5-1s/day.
Its pretty much perfect, winds very effectively, silente and reliable.
