Abstract: A kit for use in selecting a proper spring bar for use in connecting a watch band to a watch case, and including a container holding a supply of spring bars of different lengths and types, a gauge part having portions of different widths adapted to be received within and measure differently dimensioned recesses or gaps in a watch case into which a band is to be connected, and coding markings on the gauge part and bars indicating which bar in the container will fit a particular case which has been measured by the gauge part.

Abstract: A machine for painting coding stripes on watch spring bars or other similar articles and which includes a rotary transporting structure preferably turning about a horizontal axis and mounted to receive the articles to be painted successively at an upper pick-up location and progressively advance the articles downwardly to a second location at which painting means form stripes on the articles, with ultimate delivery of the painted articles to a collection point, and with the transporting structure desirably including two wheels which are relatively axially adjustable to receive and hold articles of different lengths.
