Amanico presents a compelling comparison between two vintage legends: the Patek Philippe Ref. 3417 and the Jaeger-LeCoultre Geophysic Ref. E 168. His post delves into the nuances of these highly desirable amagnetic and chronometer-certified manual-winding watches, highlighting their distinct characters and appeal to collectors.
These 2 are legends for those who collect amagnetic and or manual winding chronometers.
Two signatures, " amagnetic " and " Chronomètre ".
Two great brands, Patek and Jaeger.
Two great references as well.
The Geophysic has the advantage of being ALSO a Chronometer, the Patek has a better decorated movement.
Both are 35 mm big.
Both are highly desirable.

The Patek Philippe Calatrava reference 3417 is an antimagnetic timepiece. This reference is distinguished by its specific antimagnetic properties.
This reference features a steel case. The dial is noted as a radium dial. No further details regarding the movement or case architecture are provided.
The Patek Philippe Calatrava reference 3417 appeals to collectors seeking a specific antimagnetic Patek Philippe model. Its characteristics are defined by its reference number and antimagnetic designation.
How did their amagnetic properties compare? Geophysic 1958 tribute has 600 gauss protection (less than the modern milgauss, but I do not know what the original rolex milgauss was, but it was not 1000 gauss either!), which I believe is same as the original. And I do not know what the Patek protection was. Can you fill in all the blanks? Thanks, Nico... And parenthetically, are small second movements somehow easier to manufacture/service than central seconds? Do you think the Patek small seconds m
especially considering that JLC one made the movements for all of the holy trinity..
And reminds me of my key objective for coming year.
They have this charm I like a lot and they are definitely models that find a nice place in a collection of both brands. Thanks for the pics Nicolas. Best, Mark
These tool watches are becoming very desirable!! 3417 vs 666 I have not seen the geophysic irl
