On this page, also a note about how on most watches, the balance bridge will be considered its own entity and will not affect the classification of the movement type designation. For example, all full plate movements will also have a distinctive balance bridge.
  • Movement Types
    • Full plate - watch train is covered completely, or with a small aperture to the center wheel, with the top plate
    • Split (or 3/4) plate - top plate is split into 2-3 large segments that will cover most, but not all, of the watch train
    • Bridge - one larger top plate (the barrel bridge) will cover the main spring barrel with smaller, finger-like bridges that will extend from the side of the movement to stabilize the other gears of the watch train
    • Bar-style - All top plates are bridges that stabilize the gears of the watch train along with the winding barrel. In general, these movements will also be key wind

  • Damascene Themes
    • Brushed (or no damascene) - simply finished plates and/or bridges that have a very light texture evenly placed over each surface
    • Bar style - straight or diagonal lines in varying width across the plates and/or bridges creating a bar-style pattern
    • Checkerboard - horizontal and vertical lines in varying widths that intersect to form a checkerboard-style pattern
    • Concentric circle - circles, either simple or with fancy wavy or filigree styles, that expand from the center of the movement out to form a "bull's eye" of concentric circles
    • Other
On this page, also a note about how on most watches, the balance bridge will have decorative designs, usually floral or geometric, engraved across it that are separate from the plate and/or bridge damascening.
