    Is it signed or dated? These are usually horological school projects.

    Thank you Jerry.
    Makes sense. If it was made by a student. Must have been advanced class. LOL!
    No names or numbers at all. Bought at a Mart several years ago.

    Usually models will have enough components to show the escapement action. Often that is a small spring hiding underneath the escape wheel.

    Your detent does not appear to be functional since the locking would need to more toward the escape arbor under the influence of the passing spring. I think if it were moved to the right of the tip of the detent it would work correctly and show the action.

    They look like they could have been spare parts for a chronometer and a larger precision balance wheel clock that someone arranged to make the display. The diameters of the two escape wheels seem to be around 15 and 20 mm respectively.
