What is the Santos Octagon Ref. 2965?

The Santos Octagon in one metal: a round case of 29 to 30 mm with an octagonal bezel, a white dial with Roman numerals and a date at 3 o'clock, and an automatic movement, on an integrated bracelet. Auction houses and dealers catalog it in 18k yellow gold, often set with stones, and in stainless steel throughout.

How is the 2965 different from the 2966?

By metal. Both are automatic Santos Octagons of about 30 mm with a date at 3 o'clock. The 2966 is stainless steel with an 18k yellow gold octagonal bezel and a steel and gold bracelet; the 2965 is one metal throughout, 18k yellow gold or stainless steel. The case number, which begins with the reference, tells them apart.

Is every Ref. 2965 gold?

No. Most auction records describe yellow gold, but Fellows has sold a stainless steel example whose case number begins 2965, and Analog/Shift has sold two steel examples as ref 2965. A gold 2965 is gold throughout and a steel one is steel throughout; a steel case with a gold bezel is the 2966.

What should the case back read?

A case number that begins with the reference, such as 296502365, which Antiquorum recorded on a gold example, or 296518193, on a steel example Fellows sold. One gold example commissioned by the Omani Royal family has an 8 in front of the reference.

What should I check before buying a Ref. 2965?

The case number on the back; that the case, bezel and bracelet are all the same metal; on a gem-set example, whether Cartier set the stones, which catalogs often do not say; that the automatic winds and keeps time and the date at 3 o'clock changes cleanly; and the bracelet for stretch and a folding clasp that closes firmly. A dial whose color has changed with age, sometimes called tropical or ghost, is a matter of condition, not a separate version.

Visual Description

The Ref. 2965 is the Santos Octagon in one metal: a round case of 29 to 30 mm with an octagonal bezel, in 18k yellow gold or in stainless steel, on an integrated bracelet of the same metal with a folding clasp. The standard dial is white, with Roman numerals and a date window at 3 o'clock, under blued steel hands. Gold examples are often set with stones, with diamond-set or hardstone dials, or with rubies on the bezel and bracelet.

Reference Significance

The 2965 sits beside the two-tone Ref. 2966, a 30 mm automatic Santos Octagon in stainless steel with an 18k yellow gold bezel and a date at 3 o'clock. The 2965 is the same design in one metal throughout, and auction records describe it most often in yellow gold. Its case number runs straight on from the reference, as on the 2966; Antiquorum recorded 296502365 on a gold example.

Catalogs mostly call it the Santos Octagon; Fellows sold a steel example as a Santos Ronde.

Historical Context

Dated examples run from the 1980s, the decade Monaco Legend and Eppli give for gold examples, through about 1990 and about 1995 to the 2000s, where Antiquorum dates a ruby-set example; a dealer dates two steel examples to the 1990s. Exact production years are not established.

One gold example, commissioned by the Omani Royal family, carries a Khanjar crest on its dial.

What to Look For

Case number: The case number on the back should begin 2965.

Metal: The case, bezel and bracelet should all be the same metal. A steel case with a gold bezel is the 2966.

Stones: On a gem-set example, ask whether Cartier set the stones. Bulang & Sons describes a factory diamond-set bezel on one example, but other catalogs do not say who set the stones, and Eppli calls the diamond-set gold dial on one example custom-made.

Movement: The automatic should wind and keep time, and the date at 3 o'clock should change cleanly. Calibers are cited as the ETA 2671 and the Cal. 90, so look at the movement itself.

Dial: A dial whose color has changed with age, which listings sometimes call tropical or ghost, is a condition issue rather than a separate dial version.

Bracelet: Check for stretch and replaced links, and that the folding clasp closes firmly.
