Cal. 149 is one of a family of cam switching chronograph movements produced by Landeron. It is closely related to the preceding Cal. 48 and contemporary Cal. 148 but uses a conventional start/stop button rather than combining stop and reset. The similar Cal. 189 adds a date complication.Images are taken from official publications and are used here for commentary and educational purposes. Copyright is held by the original owner as noted.
