Patek Philippe Perpetual Calendar 3945/1 Original Accessories
Automatic Cal. 240 Q - original gold mesh bracelet - 36 mm gold case
The reference 3945 is among the most elegant interpretations of the perpetual calendar by Patek Philippe. Unlike the better-known 3940, it was delivered from the factory with an integrated gold bracelet – in this case a high-quality mesh bracelet in 18k yellow gold. Particularly noteworthy: the bracelet is explicitly mentioned in the Extract from the Archives, clearly confirming the full originality of this rare configuration.
The opaline silver dial stands out for its perfect balance and classical clarity. The harmoniously arranged displays – day of the week and 24-hour indication at 9 o’clock, month and leap year at 3 o’clock as well as the date with integrated moon phase at 6 o’clock – create a composition of remarkable aesthetics and excellent legibility. The finely applied indices and slender dauphine hands further emphasize the elegant character of this watch.
Inside operates the caliber 240 Q – an ultra-thin automatic movement with micro-rotor, regarded as one of the most important perpetual calendar movements in modern watchmaking. It combines the highest level of technical complexity with outstanding reliability, while its slim construction enables the watch’s refined profile.
The 36 mm case in 18k yellow gold impresses with its well-balanced proportions and wears very comfortably on the wrist in combination with the smooth mesh bracelet. The seamless integration of case and bracelet gives the watch a particularly elegant presence – understated yet unmistakably luxurious.
