The movement, caliber RTO 27 PS, incorporates two of the most coveted complications, the minute repeater and the tourbillon. The unparalleled resonance and exquisite tone of the minute repeating chime undoubtedly appeal to the most discerning collector. Furthermore, the gravity-defying tourbillon admired through the sapphire crystal case back, allows the watch to achieve chronometer-like accuracy. For technical reasons, Patek Philippe chose to conceal the tourbillon, rather than revealing it through an aperture on the dial-side.
Reference 3939 is housed in a 33mm case with a beautifully proportioned enamel dial. Despite the contemporary trend for larger dials, it is a perfect contemporary classic and illustrates timeless sophisticated technical achievement by Patek Philippe.
The present watch is from the later series of reference 3939 and fitted with a larger crown that was introduced to prevent over-winding the mechanism.
Consigned by an extremely important collector, the present reference 3939 is one of the handful examples that have returned to the market in pristine condition and is repeating in phase with a beautiful tone and clarity.
