The Elgin 3 watch movement is available in both open-face and hunter calibre designs. It offers the option of including a Breguet hairspring and a bimetallic screw balance. Although not listed in common registers, the similar Buser 19''' with an equivalent plate layout is mentioned by Flume, and Ronda mentions the Buser 19'''Nidor, both measuring approximately 6.5mm in height. The Buser 105 and 106 calibres, with a different layout but the same height, are more commonly listed. Stem wind and set functions are included, along with a subsecond display.
