The Octagon is a seldom seen watch in the Santos line and is one of the affordable distinctive luxury watches. It is beautifully styled and its eight-sided bezel is suggestive of the iconic Audemars Piguet Royal Oak. Not a large watch, this mens Octagon measures 31mm wide and the crown and guards add a couple more millimeters. It features a stainless steel case with 18K bezel, classic white Roman dial with blue steel "epee" hands, sapphire topped crown, and mechanical movement. Unlike the quartz version of the Santos, this more desirable mechanical example possesses an automatic movement and in a way showcases the timeless art of traditional watchmaking. The watch is gorgeous condition, rating about a 9.7 / 10. The movement has just been freshly overhauled.

Named "Jeweler to the Kings and the King of Jewelers" by Edward VII, Cartier has attracted Russian, British, and Indian aristocrats as well as some of the most esteemed celebrities since Louis-Françoise Cartier founded his namesake brand in 1847.

During the 1930s, Cartier’s directrice-artistique Jeanne Toussaint sent Cartier designers to the zoo where their innovations led to Cartier’s renowned panther and tiger designs. When Duchess of Windsor commissioned Cartier to create two 3-D panther brooches (one composed with cabochon emeralds, the second with diamonds and sapphires) in 1948, it was soon after that the panther became the symbol of Cartier.

Beyond the symbolic panther, two of Cartier’s most desired collections remain the Cartier Tank and the Cartier LOVE Series.
