Visual Description
The Ref. 1320 is the small Panthère in stainless steel, 21 to 22 mm wide, with a square case whose back is secured by eight screws. Antiquorum gives 22 × 30 mm and a thickness of 5 mm. The case runs into an integrated steel link bracelet that closes with a signed double folding clasp.
The dial is silvered, cream or ivory, with Roman numerals, read by blued steel sword hands. Antiquorum notes Cartier's secret signature at X on its example.
Reference Significance
The 1320 is the small size of the steel Panthère, below the medium Ref. 1310 and the Jumbo Ref. 1300. It shares its size with the steel and gold Ref. 1120, and Fellows catalogs both on the Cal. 157 quartz movement.
Historical Context
Cartier introduced the Panthère in 1983. Dated 1320s run from about 1990 to 2003: Smith & Singer dates one to about 1990, and Antiquorum records another as made in 2003 and sold new in November 2004.
What to Look For
Case back: It should carry 1320 and a serial number.
Bracelet and clasp: The steel bracelet should have all its links and a signed double folding clasp that closes firmly.
Dial and hands: The Roman numerals should be clean and the hands blued steel.
Movement: It should be quartz and running. Smith & Singer catalogs it as the Cal. 157, with the case, dial and movement signed.
