The patent number and initials between the plates refers to the patent taken out by Bahne Bonnisken, the inventor of the Karrusel mechanism. The 34 minute Karrusel was designed with centre seconds hand, which was required for navigational and other scientific uses. The use of the chronometer detent escapement in the Karrusel is highly unusual and would have been difficult to construct. However this watch was entered for trial at The Royal Observatory Greenwich, from 4 July 1903 to 23rd January 1904 for purchase by the Board of Admiralty, together with 8 other watches, where it obtained first place.

Interestingly, it would appear that all these watches apart from Lindqist 108 were Karrusels with chronometer detent escapement.
