Carl Rotter surprised his wife on their wedding anniversary with a new design and named it after her: Margarete symbolizes the different phases of a relationship - the composition of various different engraving techniques. For no other design are more grinding stones required. The deep wide curve of the snail depicts the “difficult rough times”. The tender spiral represents diligent patience. Egraving both the spiral and the snail, one must not let go, restart or deviate. Ah, so it is in life! Upon turning the glass to look "back" through the clarity of the present, those hurdles suddenly seem very small.
