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

No, I don’t, but I’ve heard the 1120 is based on the 2892-A2 and would like to compare them. I may be doing a watchmaking bench test on the 1120.

Yes, it’s also the Omega 1120. A very accurate and reliable chronometer grade movement as used by Omega. Only downside is it’s not technically an in-house movement.

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’m happy to report I have added another watch using the 2892-A2 to my collection. It’s a new Omega Seamaster 300m Diver with the Omega 2500D Co-Axial modification. I passed on the 2018 Seamaster with the new Master chrono movement due to the overall case size, I have a thin wrist and 41 was my max. I’ve had it 3 weeks and am thrilled with it.

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.

I bough an elaborated grade one on eBay and after 3 days of wearing the watch I mounted it into and regulating it based on observations I obtained +2s/d going on from there. I’m very surprised and impressed. (new to watches)

The mainplate and bridges are probably brass with a gold flash plating. You bought just the movement? What watch is it for?
