Introduced in 1981, the Ref. 3450 represents the evolution of Patek Philippes pioneering self-winding perpetual calendar. Building on the historic Ref. 3448, it added a discreet leap-year indicator at 3 oclockan innovation that would define the modern perpetual calendar. Produced for just five years in very small numbers (fewer than 250 examples), the 3450 is among the most studied and coveted perpetuals of the late 20th century.
At 37.5mm, the case retains the clean architecture of the 3448, with its wide bezel and sculptural lugs. Inside is the refined caliber 27-460Q, Patek Philippes celebrated micro-rotor movement. Early examples used a dot system for the leap-year display, while later models employed Roman numeralsa small nuance that marks the references evolution.
This 3450 dates to 1985, near the end of the references production, and is accompanied by its Patek Philippe Archive extract. The watch is in remarkable condition with sharp case lines and a clean, balanced dial. A clear sapphire caseback allows an unobstructed view of the beautifully finished micro-rotor movementan elegant detail appreciated by collectors.
As the final expression of the micro-rotor perpetual line and the bridge to Pateks modern era (preceding the Ref. 3940), the 3450 occupies a special place in the brands history. Understated, technically significant, and produced in very limited numbers, it remains one of the most compelling perpetual calendars ever made.
