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 Certified Pre-Owned mens Octagon measures 31mm wide and the crown and guards add a couple more millimetres. It features a stainless steel case with 18K gold octagonal bezel, classic white Roman dial with blue steel "epee" hands, sapphire topped crown, and mechanical Cartier 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.

It has fully Cartier parts down to the original dial, hands, and crown and presents as gorgeous condition - overall about a 9.7 out of 10. On the wrist it presents nearly like new.

It has been freshly fully serviced by a Master Watchmaker (a $495 value). Note that the waterproofing gasket in the crown normally makes this model stiff to wind, even after servicing. If you would prefer never to handwind it, it's a great candidate to be placed on a watch winder for convenience.

It is keeping time on par with a brand new Cartier watch in our testing position.

Included with the purchase is a one-year C.O.T. international warranty on the movement and its function, a full-page custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

Cartier Santos:
Cartier created the Santos in honor of the famous Brazilian aviator Alberto Santos-Dumont. Alberto Santos-Dumont, a true daring aviation pioneer, flew in France and Europe in some of the first prototype airplanes.
