Cartier Santos Octagon LM Combination Automatic Winding with Permanent Warranty, Complete Service Performed
The Santos Octagon, no longer in production, features a distinctive octagonal shape with sharp angles on a round form that is truly unique.
This particular model is a Santos Octagon LM with a mid-period bracelet, not a gadroon.
It's quite rare to find one in this condition with a lifetime warranty certificate.
A notable feature is that it underwent a complete service in November 2024. (This particular watch received a free complete service using the lifetime warranty certificate.)
Equipped with the same automatic movement as the Santos Galbée, the Santos Octagon boasts an unusual octagonal case for Cartier.
Recently, there has been a resurgence of interest in this piece, making it highly sought after.
It's a must-have for those who appreciate luxury sports watches.
This watch underwent a complete service at Cartier in November 2024.
As it's a vintage item, there are minor scratches on both the case and bracelet, but polishing has been kept to a minimum to preserve its original character.
Despite minor scratches, the case and bracelet are in good overall condition with few major dents or deep scratches.
There is almost no sagging or stretching in the bracelet, indicating excellent condition and suitability for daily wear.
The crystal is also in beautiful condition with no noticeable scratches.
The dial was replaced with a new one during the complete service in November 2024, so there are no cracks or stains whatsoever. It appears to be in very clean condition.
Overall, it's a piece in exceptionally good condition.
