At times when quartz was threatening to change the industry forever, Audemars Piguet carried on with what they do best: extraordinary mechanical watches. This extra-slim timepiece embarks the caliber 2120QP, a sophisticated Jaeger-Lecoultre 920-based mechanical tour-de-force which was also used in the Royal Oak 5402 models and Patek Philippe Nautilus 3700. The historical importance of this reference, its timeless aesthetic with the distinctive four subsidiary dials layout, the elegant case design and diameter would make this piece a significant addition to any collection.
