The present Patek Philippe reference 3445/6 is a refined and rare expression of the Calatrava line, elevated here by its waterproof construction and its fully integrated 18k yellow gold bracelet. Crafted in 1968, the watch embodies the classical purity of the Calatrava aesthetic, while revealing the technical sophistication of Patek Philippe’s mid-century automatic production. Its gold dial, understated yet luminous, is complemented by applied indexes and a discreet framed date aperture at three o’clock, balancing functionality with timeless elegance.

At the heart of the watch lies movement number 1126988, the celebrated calibre 27-460 M with 37 jewels. This self-winding movement represents one of Patek Philippe’s most accomplished automatic constructions, distinguished by its efficiency, beauty of execution and the harmonious oscillation of its rotor. Housed within case number 324291, the watch measures 35 millimetres in diameter and carries a reassuring presence on the wrist, enhanced by its weight of 118.06 grams in solid yellow gold.

The integrated bracelet, also in 18k yellow gold and signed by Patek Philippe, forms a seamless continuation of the case. With its gently tapered links and an approximate total length of 190 millimetres, it contributes to the watch’s sculptural unity, transforming it into a complete object of elegance rather than a mere timekeeping instrument. The dial, case and movement are all signed, affirming the piece’s authenticity and coherence.

Accompanied by its original Patek Philippe certificate, this reference 3445/6 stands as a particularly attractive and rare example within the waterproof Calatrava family. It unites mechanical excellence, aesthetic restraint and the luxurious presence of a fully integrated gold bracelet, embodying the enduring values of the manufacture in a form both practical and unmistakably refined.
