Lot Essay
Before the introduction of the Nautilus, Patek Philippe had only produced two references available exclusively in stainless steel: reference 3418 and reference 3417.
Launched in 1958 and produced until around 1970, reference 3417 holds a prestigious place in Patek Philippe's history as the brand’s first series-produced 'Anti-Magnetic' wristwatch. Exclusively crafted in stainless steel, it symbolized innovation and excellence. At the time of its debut, the 'Amagnetic' feature was a true mark of distinction, proudly displayed on the dial.
The early models featured the cal. 12 AM 400 movement, while from 1960 onwards, the caliber 27 AM 400 took over production until the series was discontinued. Both calibers were equipped with a gold or beryllium lever escapement and shielded by a soft iron (permalum) cap. Remarkably, these movements were engineered to resist magnetic fields of up to 450 oersteds - more than four times the magnetic strength required to halt a conventional watch, underscoring their exceptional performance and reliability.
