Manufacture Piaget 551P self-winding mechanical movement with small seconds and power-reserve indicator.
A development of the 500P, the 551P is a self-winding movement distinguished by the addition of two small complications: an off-centred 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, bevelled bridges and blued screws adding the finishing touches to this movement are reminders of the Swiss watchmaking brand's high aesthetic values.
