Ref : 551P
A development of the 500P, the 551P is a automatic movement distinguished by the addition of two small complications: an off-centered small seconds at 10 o'clock, a Piaget signature feature and a power-reserve indicator at 6 o'clock. It is also fitted with a balance stop. The circular Côtes de Genève, circular-grained mainplate, beveled bridges and blued screws adding the finishing touches to this movement are reminders of the Swiss watchmaking brand's high esthetic values.
