NOTES:  The usual method of dating a case by the case serial number does not work with this watch, which has the atypically short serial 4910.  It should also be noted that the case does not include either the 1924 or 1927 patent dates, one of which should be present in any 1920s model dated after 1925.  Therefore, the date on this watch has been determined by the movement date code, taken in consideration with its overall style and advertisements dating to that period.  1929 is an appropriate date for this watch.
