Cartier Santos-Dumont LM Extra-Flat Men's SWISS Dial
Among the Santos-Dumont series, the masterpiece slim model "Extra Flat" is powered by the Frederic Piguet Cal. 21, making it a popular model among enthusiasts. This particular piece features a Swiss dial without guilloche, making it a relatively affordable option within the Extra Flat range.
This type has a Swiss dial without guilloche, and the dial material is the same pure white, porcelain-like material as the Paris dial. It is essentially constructed in the same way as the CPCP Santos, Swiss guilloche dial, and Paris dial Santos models.
The overall condition is very good. The dial shows no dirt or discoloration, but some light cracking is visible in certain areas. This is barely noticeable, only under certain lighting conditions or upon close inspection. Even considering this, the condition is still considered good. The case has undergone minimal polishing. There are light, minor scratches on the case and bezel. The edges are still sharp. The original case condition has been maintained and is in beautiful condition.
