Visual Description
The Tank Cintrée is a Tank drawn out into a long rectangle and curved from end to end so that it follows the wrist. In its largest size the case measures about 23 × 46 mm. Dials carry Roman numerals graduated to the long shape, with an inner minute track; one white gold example of the 1930s has luminous Arabic numerals instead.
Reference Significance
This page covers the Cintrée's early production, which carries no reference number. Phillips calls the 9-ligne Grand Tank Cintrée the largest of the first Cintrées, which it says came in three sizes set by the movement, and describes the European Watch and Clock Co. caliber of its 1927 example as supplied by LeCoultre.
Platinum and gold cases are both documented: platinum in the 1920s, 18k yellow gold from about 1925 to about 1950, and 18k white gold in the 1930s.
Historical Context
Phillips and Sotheby's date the Cintrée's introduction to 1921. The dated early examples begin about 1925 and run to about 1950.
Later Cintrées without reference numbers also exist, among them one of 1965 and one of about 1976, and fall outside this page's range.
What to Look For
The hand-stamped Cartier numbers on the case back should match those on the clasp, as they do on examples Phillips and Sotheby's have sold. The movement should be hand-wound and, on most early examples, signed European Watch & Clock Co.
Check the case metal against its marks, and look closely at the dial: one dealer described the dial of a platinum example of about 1926 as reprinted. Sight along the case for dents or flat spots in the curve.
