"I have great pleasure in being associated with the revival of the Perrelet brand by being involved in the development of a limited retrograde second series, cased in white or pink gold. This pleasure is all the greater given that, today more than ever before, this brand pays tribute to Abraham-Louis Perrelet, one of the greatest watchmakers of his time and inventor of the automatic winding system which I have reinterpreted through this parallel double rotor mechanism." - Paul Gerber
