Extended Search, Archive: Movements  
Search string
If you want to search in the texts simultaneously with the search after visual and technical features, enter the search string here. If you want to search after several complete or partial words, separate them by blanks.
Basic Shape of Movement
Mark below the image matching the basic shape of the movement in question best. Only the red lines are important for the selection.If the shape is uncommon, you can mark several images, if they are similar to the movement in question. If you aren't sure which matches best, don't mark any.
  Position of Balance
Mark below the image matching the position of the balance staff in relation to the stem, seen from the movement back side. Important for the selection are the red limit lines.If the movement has a horizontal winding arbor (e.g. key winding, back winding), the line from movement center to winding arbor is also the reference.
The round basic shape represents all others.
Balance Cock or -Bridge
Mark below the image matching the balance cock or -bridge of the movement in question best. Only the red lines are important for the selection. Thin lines near the edge demonstrate how the part may look there. Important is the orientation of this part, i.e. whether the rotation direction from the mounting point towards the balance bearing is oriented clockwise or counter clockwise.If the shape is uncommon, you can mark several images, if they are similar to the movement in question. If you aren't sure which matches best, don't mark any.
The round basic shape of the movement and the location of the cock represent all others.
Hairspring Stud Carrier
Mark below the image matching the stud carrier of the movement in question best. Only the red lines are important for the selection.If the shape is uncommon, you can mark several images, if they are similar to the movement in question. If you aren't sure which matches best, don't mark any.
Winding / Setting
Mark below preferably all images containing details of winding- and setting mechanism applied in the movement in question. These details ar drawn red.For automatics don't mark the manual wind symbols in the first line.
The round basic shape represents all others.
  Stem Release
Mark below the image matching the position of the stem release. The red dot represents the release, regardless whether it is a screw, a button, an ear, or a lever.Examples for external stem release are old pocket watches, especially American, or back winders.
The round basic shape represents all others.
Number of Holes in Setting-Lever Spring and/or Setting Bridge
Enter number

Enter number
Of course you shouldn't remove the dial, to count the number of holes. If this number(s) are unknown leave the fields blank. If setting-lever spring and setting bridge are separate parts, you should enter the hole numbers of both in any order. In most movements setting-lever spring and setting bridge are identical. Others have a setting bridge but no setting-lever spring. In these cases enter just one number. Some movements have neither nor; these are efficiently found with the hole number 0.
Diameter or Width and Length
up to 13mm
12 ... 22mm
20 ... 35mm
more than 32mm
Mark the range(s) valid for the main dimensions of the movement. For round movements one range will do, for form movements sometimes two ranges are valid.

The program searches for the matching mounting diameter, but as the ranges overlap, measuring needs not be very accurate. Usually the dimensions taken from the visible back side will be sufficient.
Escapement, Electrical/Electronical Control
swiss lever
pin lever
English lever
Glashütte lever
cylinder
verge
chronometer
duplex
balance, electrical control
balance, electronical control
tuning fork
quartz
If escapement or conrtol is not known, don't mark any checkbox.

Movements where more than one feature match, are rare, e.g. electronic balances or tuning forks with quartz control.

Rather strange escapements are probably better be found with the text search feature.
