The Chronodrometer, patented in 1859, was Dennison's attempt at producing a variation on the typical American watch. The chronodrometer had the inconvenience that, when the timing device was used, normal time was interrupted, so that the watch had to be reset. As a result this model never achieved great popularity and had a relatively limited production.
