On the enamel version, the time is indicated by the open-tipped Breguet hands, in addition to the Breguet Arabic numerals, both invented by the master himself. The guilloché model combines “Clous de Paris” and basket motifs, surrounded by Roman numerals. All versions contain a discreet secret signature, another legacy from A.-L. Breguet, and a gauge of authenticity. On the technical side, this model features an extra-flat movement that has been decorated by hand, the oscillating weight of which is off-centred.
