Cartier Santos-Dumont LM Extra-Flat Men's Guilloche SWISS Dial
The "Extra Flat" is a thin model and a masterpiece within the Santos de Cartier series.
It is extremely rare and a highly sought-after item even overseas.
Equipped with a Frédéric Piguet Cal. 21, it is a popular model among enthusiasts.
The dial has a very faint stain around the 11 o'clock position, but it is not noticeable when worn.
The case has not been over-polished, so it retains its sharp edges, making it
in beautiful condition.
Its thinness allows it to fit comfortably around the wrist, a graceful form characteristic of Cartier.
