Object description

Case Construction and Exterior Hardware

This Breguet Classique reference 3657 features a 40 mm round case fashioned from yellow gold, bearing case number 2'664L and dated by the cataloguer to circa the 2000s. The cataloguing notes that the case exhibits light scratches and nicks throughout, while the hallmarks remain defined.

The watch is fitted with a yellow gold Breguet deployant clasp described as showing light scratches and wear throughout, with crisp, well-defined hallmarks. The original strap is not included in the sale; instead, the piece is delivered on a Christie's branded replacement strap.

Dial Architecture and Visible Features

The timepiece features a silvered engine-turned guilloché dial configured with an off-centred primary time display displaying Roman numerals and blued steel Breguet-style hands. At the lower portion of the dial, an open aperture at 6 o'clock reveals the tourbillon cage secured under a horizontal bridge.

Flanking the tourbillon aperture, the dial is signed 'BREGUET' and numbered 'No 2664'. The lower margin is marked 'SWISS GUILLOCHE MAIN'. Complications integrated into the dial include a power reserve indicator and a retrograde 24-hour indication. A scratch is noted on the crystal near twelve o'clock, while the dial and hands are described by the auction house as showing virtually no signs of wear.

Reported Movement and Documented Limitations

The wristwatch is powered by a manual-wind movement supporting the tourbillon, power reserve, and retrograde 24-hour indication. Calibre designation, jewel count, and internal movement numbering are not recorded in the source listing.

The auction house condition report notes that the movement was running at the time of cataloguing consistent with the age of the watch, but it was not tested for timekeeping accuracy and a service is recommended. Additionally, the lot includes neither manufacturer box nor papers.

Evidence for this section
  • “MOVEMENT: Manual”
  • “The movement is running at the time of cataloging, consistent with the age of the watch. The movement has not been tested for accuracy.”
  • “A service is recommended given the age of the watch.”
  • “BOX: No”
  • “PAPERS: No”

Open research questions

  • What specific calibre reference (e.g., Calibre 558 or derivative) powers this Breguet reference 3657, and what is its individual movement serial number?
  • What specific gold hallmark standards and maker marks are present on the case band, caseback, and deployant clasp?
  • Does Breguet's archival ledger record the exact production and sale date for case serial 2'664L?
