    ETA 2824-2 COSC or not?

    I have an Antea Creme with the 2824-2 movement with blue screws. My understanding is that this is the top movement (based on the sticky tread above) but I don't have COSC papers with it. Does that mean that my movement is not "Certified"? I bought it second hand so the papers could have disappeared along the way, I guess.

    Can you guys educate me please? Thanks in advance.

    There are several grades of ETA movements: Base, Elabore, Top and COSC.

    One of the first movements every watch collector should be familiar with is the ETA 2824-2, which is an automatic movement used in a multitude of timepieces. It’s offered in four grades that include the Standard, Elaborated, Top, and Chronometer. Each of them costing more than the last but all featuring a 25 jewel movement. The biggest differences are the quality of the barrel spring, its shock resistance capabilities, the balance wheel and hairspring as well as the regulator and pallet stones. When it comes to the movement, you get what you pay for, and it’s important to recognize which movement is in the watch you plan to purchase.
    From your link above. Great info! Thanks.

    So mine is the Top and not COSC. Appreciate the help both of you.

    Stowa used to offer COSC certified movements in their watches in the past.

    But some time ago Swiss Contrôle Officiel Suisse des Chronomètres (COSC) changed their policies. Since summer 2011 a certification is only issued for swiss manufacturers (read: the movement must be encased in Switzerland) if requested by the Swiss manufacturer. Documents issued by the COSC are optional, for more info see COSC website.
