Accompanied by a certificate of origin from the Deutsches Uhrenmuseum, Glashütte confirming the date of sale on 6th July 1905 to H. Keim, Bad Ems for 1,027.65-M.  The chronograph mechanism is controlled by a single crown to the case side - the first depression starts the chronograph running, the second splits the hands (stopping the first of the chronograph hands whilst the other continues to run) the third depression stops the chronograph and the fourth resets both hands to the 12 o'clock/'0' position.  This differs from the split second chronograph, which can take intermediary seconds.

The present lot, No. 42624 is a part of a series of approximately 35 double chronographs produced between 1886 and 1918.
