there have been a number of repetition a minutes made by pp. many were made upon request. i speak of the tonneau shaped platinum case minuter repeater for henry graves jnr, refs 2421, 2524, ref 3979, 3974,3939,5013, 5016, 5074 and toubillion ref 3834, 3939, 5101, 5016 i have noted that that a number of comments on here that suggest that these master complications are useless in a watch and can not justify paying so much for a reference with them. it is admitted that the movement of the wrist takes the place of a tourbillion and is therefore redundant in a watch and it can be successfully argued that non one cares to listen to the chimes and gongs of a wrist watch, as this was for when electricity was uninvented and darknes reigned.
