Quantieme Perpetuel 25657BA

This Audemars Piguet 25657 proves that it is still possible to get into ultra-high end watchmaking at a relatively affordable price.

AP's introduction of the 'Quantième Perpétuel Automatique' line of ultra-thin perpetual calendar wristwatches in 1978 was one of the most significant innovations in modern watchmaking. This ref. 25657 is executed in a slim 18k yellow gold case, measuring a classic 36 mm, and features a lovely stepped bezel and elegant downturned lugs.

The white dial is the most understated of the bunch and features elegant applied 18k yellow gold stick indices and three lovely recessed sub-dials that indicate the day, date, month, and phase of the moon.
