ETA 2892.A2 Grades....

[Jimr]

Is their a meaningful difference between the ETA 2892.A2 Standard, Elabore, Top grades or is it a theoretical difference with no meaningful real world consequences?

[lysanderxiii]

I suppose that depends on whether you think being timed to have lower positional variation, lower daily rate error is meaningful in the real world.....

Oh, and the 2892A2 does not come in Standard Grade.

[Jimr]

Isn't that much more an issue of proper adjustment?

Are the very few and very limited component differences that consequential in the real world?

Any repair 'people' care to comment as well?

There are also some different materials used for different grades.

[Jimr]

That appears to be the only difference and even then only in one component.
Still do not know if any of this has any real world consequences of note.

ETA 2892 comes in different grades of quality of Elabore, Top, Chronometer. The differences in grades can range from quality of materials used, to the level of testing and regulation.

I know..Thank you...
The question remains...

If they are all well regulated (after purchase) and their appears to be only one component that uses a different material...

Does any of this translate into real world (not theoretical) differences ...durability etc...or are the differences so minor that in the real world a well regulated Top behaves just like a well regulated Elabore 2892.A2 ?

More than one component is different between the eblabore and top/chonometer grades. The balance wheel is different, as is the balance spring material, and the type of regulator.

Regarding real world differences, having the better components increases the chances that the watch will time very well. There are certainly lower grades that can be adjusted (not regulated) to perform better, but the chances of getting good results is increased with the better balance wheel and spring.

I service a lot of 2892A2 based watches from many brands, and most are top/chronometer grades. I actually don't see many that are elabore grade, but those I have serviced with that grade have had more positional variation than the top/chronometer grades do. I see more ETA 2824-2's cross my bench with the lower grades, and indeed there is a significant difference between the results with a typical 2824 standard or elabore, and one that is a chronometer.

Any notable reliability differences among 2892.A2 ?

Thanks Al for sharing!
