Visual Description
The Ref. 96061 is the ultra-thin Santos Dumont in two golds: an 18k yellow gold case with an 18k white gold bezel. Bulang & Sons and Hairspring measure it at 26 × 36 mm, and Sotheby's at 27 × 36 mm. The white dial carries black Roman numerals and is signed Paris, with the hidden Cartier signature in the VII, and the hands are blued. Bulang & Sons records a blue sapphire cabochon crown. Sotheby's offered one on an alligator strap with a buckle, and Bulang & Sons sold one with a Cartier gold folding clasp.
Reference Significance
The 96061 is the two-gold companion of the yellow gold Ref. 96054: the same large ultra-thin format on the Cal. 21, with a white gold bezel. Dealers sell both as Extra Plate or Extra Thin, and Bulang & Sons and Hairspring add the name Deux Ors for the two golds.
The 1970s Ref. 78225 is also called Deux Ors but reverses the metals, with a white gold case and a yellow gold bezel. The small Ref. 96062 has also been sold in yellow gold with a white gold bezel.
Historical Context
Sotheby's dates its example to circa 1990 and Bulang & Sons its own to the early 1990s. The start and end of production are not documented.
What to Look For
Metals: The bezel should be white gold and the case yellow gold. Sotheby's catalogs one simply as yellow gold, and some listings call the bezel steel, so check the metals and hallmarks.
Case back: It should carry 96061; a 96054 is all yellow gold.
Dial: White with black Roman numerals, a Paris signature and the hidden signature at VII.
Movement: It should be the hand-wound Cal. 21; ask for a photograph of the movement.
