    Grades of 2824-2?

    How does one visually distinguish the various grades of 2824-2? I know that the highest grade includes a serial number to be COSC compliant. But for the three lower grades how the heck do you tell them apart?

    There's no sure-fire way to do it, other than a nicely worded e-mail to the manufacturer.....A helpful indication is the appearance of the shock protection and balance wheel used. For example, this is a 'standard' grade 2824.



    Note the flower shaped shock, called 'Etachoc' and the balance wheel has straight spokes.

    This is a 'Top' grade 2824.



    The shock is different (Incabloc) and the balance wheel spokes flare out at the edges, which Eta calls 'Glucydur'

    Both the Standard and Elabore should look the same, and the Top and Chronometers should look he same, but different shocks have been used at different times, so it's not reliable. The COSC serial can be used to differentiate between Top and COSC and just about the only thing to differentiate between Standard and Elabore is the type of alloy used in the hairspring, but if you can tell those apart, you've been looking at watches for too long, LOL.

    So it's got an Incabloc shock and a straight-spoked balance wheel. Does this mean it's a Standard or an Elabore?

    I tawt I taw an Elabore

    (Based on the Incabloc and 'decorated' rotor. The general finishes seem nicer than the Standard grade 2824's I've seen, but it might just be the lighting...)

    Re: Grades of 2824-2?

    The straight spoked balance is the nickel balance (Standard and Elabore), the curved spokes are the Glucydur balance (Top and Chronometer).

    The Incabloc shock protection can show up on any grade, is an available option on the Standard and Elabore grades, but is standard on Top and Chronograph.

    There is no visual way to discern an Elabore from a Standard, all the standard parts are the same between them and both have the same optional upgrades. The only difference is the regulation requirements.

    Standard and Elabore grades can be differentiated from higher grade by the balance only, all other parts are either visually identical (can you see the different between a Nivarox 2 and a Anachron, no you cannot), or optional on the lower grades.

    Top grade can be differentiated from the chronograph by the lack of a serial number.

    Interesting info. What about the ETA 2892-based movements? Similar differentiation between the grades?

    Generally, yes, except that the 2892 is in their premiere line and is not available in standard grade.

    To expand on Lysander's comments, ETA will customize the package for a watch computer. The grades are just typical packages, but any combination of features can be ordered.

    Here's a top-grade 2824, with extra decoration as required by the manufacturer, including extra perlage, blued screws, extra engraving about positional adjustments, watch company's caliber number, and a cutout rotor.

    So given the subtlety in the physical differences between the grades one has to wonder: what is the difference in cost between the grades?

    All Top and Chronometer grades get the Glucydur balance and all Glucydur balances have curved spokes.
