Visual Description
The Ref. 1031 is the 35 mm steel Pasha: a round brushed and polished case with hinged lugs, a crown that screws down under a cap held by a security link, and a case back secured by eight screws. Bonhams catalogs a white dial with gilt baton hour markers, black Arabic numerals at the quarters, a black outer minute track and luminous sword hands, with a magnified date between 4 and 5 o'clock. Fellows catalogs silvered and brown dials with the same baton layout, and Phillips a blue dial. All three houses show it on a Cartier steel link bracelet.
Reference Significance
The 1031 sits beside the Ref. 2324 as a 35 mm steel automatic Pasha on the Cal. 049. The lots on file separate them by dial: baton markers with Arabic quarters on the 1031, Arabic numerals around the dial on the 2324. The wide range of dial colors, white, silvered, blue and brown, is the 1031's most visible trait.
Historical Context
Bonhams dates its example, case PB13749, to circa 2000 and sold it in London in February 2014. Phillips dates another, case PB13170, to circa 2000s. Fellows catalogs two more without a date. Bonhams prints the movement number 2892A2 beside the Cal. 049, the ETA base the Cartier caliber is built on. No source found gives a first or last year for the reference.
What to Look For
Read the case back for 1031 and a PB serial. Check that the crown screws down and its security link is intact, that the magnified date changes cleanly between 4 and 5, and that the luminous hands and dots have aged evenly. Look for stretch in the bracelet and a clasp that closes firmly, and ask for the service history of the automatic movement.
