Cartier Bébé Guillotine Wristwatch

Partially verified

This Cartier 'Bébé Guillotine' wristwatch, dating to the mid-1930s, features a unique concealed-dial mechanism. Originally conceived as a purse watch, this example was modified by Cartier Paris for the English market, characterized by its 18K yellow gold two-body case with black enamel accents and Roman numerals on the bezel. When the ends are compressed, dual shutters retract to reveal the dial. The watch is powered by a rhodium-plated, 19-jewel movement produced by European Watch and Clock Co. Inc., featuring fausses cotes decoration and a straight-line lever escapement. The off-white dial displays a painted minute track and blued steel Breguet hands. This piece is fitted with a deployant clasp in 18K pink gold and reflects a specialized production run where approximately 50 such pieces were adapted as wristwatches and subsequently imported to London, as evidenced by the period hallmarks found on the case.

Object description

Case and Dial Design

The watch is constructed with a solid, two-body case finished in 18K yellow gold. A defining feature of this model is the black enamel radial Roman numeral display integrated directly into the bezel. The watch functions as a concealed-dial piece: upon pressing the ends of the case, two internal shutters open to expose the dial beneath.

The dial itself is painted off-white and includes a painted minute track. Time is indicated by blued steel Breguet-style hands. The case includes hooded lugs and is paired with an 18K pink gold deployant clasp.

Evidence for this section
  • “Two-body, solid, polished, bezel with black enamel radial Roman numerals, when the ends are pressed two shutters open revealing the dial, black enamel and gold hooded lugs.”
  • “Painted off-white with painted minute track. Blued steel Breguet hands.”

Movement and Mechanical Specifications

The internal mechanism is a 7 3/4''' movement manufactured by the European Watch and Clock Co. Inc.

Technically, the watch utilizes a straight-line lever escapement and a cut bimetallic balance, managed by a flat blued steel balance spring and an index regulator. It is adjusted to 8 positions. The movement is signed by the European Watch and Clock Co. Inc., while the dial bears the signature of Cartier.

  • “7 3/4''', rhodium plated, fausses cotes decoration, 19 jewels, straight line lever escapement, cut bimetallic balance, 8 adjustments, blued steel flat balance spring, index regulator.”

Provenance and Historical Context

This watch belongs to a small production run of approximately 50 pieces modified by Cartier Paris from an original purse watch design into a wristwatch format. These pieces were specifically intended for the English market and imported into London in the 1930s, as confirmed by the presence of English import hallmarks on the case.

The watch is officially identified by its serial number and model designation.

Evidence for this section
  • “Approximately 50 pieces of this kind were modified by Cartier Paris and were sent to Cartier London (import and date English hallmark), and were sold there in the 1930s.”
  • “Grading System Grade: Case: 3-24 Good Slightly chipped Movement: 3* Good Overhaul recommended, at buyer's expense Dial: 3-24-01 Good Slightly chipped”

Open research questions

  • What specific mechanisms allow for the synchronized opening of the dual shutters?
  • Are there variations in the enamel work on the bezel across the known 50-piece production run?
