Visual Description
The Ref. 187906 is the 26 mm ladies' Cougar: a round brushed and polished steel case with a fixed yellow gold bezel set with eight decorative rivets, a crown with a cabochon and a case back secured by eight screws. Bonhams catalogs a silvered dial with black Roman numerals, a minute track, a date aperture at 3 o'clock, blued sword hands and a secret signature at 10, and Piguet a matt silvered dial. Wright catalogs a cream dial. The steel and gold brick-link bracelet closes with a signed double folding clasp.
Reference Significance
The 187906 is the ladies' size of the steel and gold Cougar, the 26 mm counterpart of the 33 mm Ref. 187904 and the steel and gold counterpart of the 26 mm gold Ref. 887906. The Ref. 119000R matches it in size, metals and movement; no source found ties the two numbers.
Historical Context
Bonhams dates its example, case No. 007412, to circa 1990 and sold it in London in November 2023. Piguet dates another, n° 001749, to the 1990s or 2000s and catalogs the Cal. 87 quartz movement with 7 jewels, as Bonhams does. Wright catalogs a third without a date. No source found gives a first or last year for the reference.
What to Look For
Read the case back for 187906 and a serial. Check the gold bezel and its rivets for wear and polishing, the bracelet for stretch and the clasp for a firm close. Check that the date changes at 3 o'clock and that the quartz movement runs.
