Object description

Case and Exterior Construction

The Piaget Black Tie Rectangle A L'Ancienne is housed in a rectangular, curved case manufactured from 18K white gold. Measuring 31 x 46 mm, the case is constructed in two bodies and features a case back secured by eight screws. The exterior is extensively decorated with round diamonds, which are pave-set across the bezel, the sides, and the hooded lugs.

The timepiece is fitted with a sapphire crystal and includes an 18K white gold deployant clasp. The watch is water-resistant, as specified in the auction documentation.

Evidence for this section
  • “Two-body, solid, case back with 8 screws, hooded lugs, bezel, sides and lugs pave-set with round diamonds”
  • “18K white gold and diamonds wristwatch”

Dial and Complications

The watch face is finished in black and features silver painted radial Roman numerals for hour indication. The central portion of the dial is pave-set with diamonds. The timekeeping display is augmented by several complications, including a retrograde 30-seconds display positioned at the 12 o'clock mark.

At the 6 o'clock position, the dial incorporates both a power reserve indicator and a date aperture. The watch uses white gold dauphine-style hands to indicate the time.

Evidence for this section
  • “Black with painted silver radial Roman numerals, diamond pave-set center, silver retrograde seconds sector at 12 and power reserve sector at 6, aperture for the date at 6.”
  • “White gold dauphine hands.”

Movement and Condition

The internal mechanism is the Piaget Caliber 561P, a self-winding movement featuring 26 jewels. The movement is finished with rhodium plating and fausses cotes decoration. Technically, it utilizes a straight-line lever escapement, a Glucydur balance, and a self-compensating balance spring.

The auction description assigns an 'Excellent' grade to the watch as a whole, specifically noting the dial as 'As new' and the movement as 'As new', though it also records a recommendation for an overhaul.

Evidence for this section
  • “Cal. 561P, rhodium plated, fausses cotes decoration, 26 jewels, straight line lever escapement, Glucydur balance, self-compensating balance spring.”
  • “Overhaul recommended, at buyer's expense”

Open research questions

  • What specific production year does the case serial number 916133 correspond to within Piaget's internal records?
  • Does the 'A L'Ancienne' designation refer to a specific finish technique used on this model's case?
