Dubois-Dépraz 100th Anniversary Grande Date Chronograph Wristwatch

Partially verified

This Dubois-Dépraz gentleman's wristwatch was produced in 2001 as part of a limited edition of 100 pieces celebrating the manufacture's centenary (1901–2001). Cased in gilded stainless steel with a vertical tonneau profile, the auctioneer reports it houses the self-winding calibre 4500, based on an ETA 2892 A2 with proprietary Dubois-Dépraz modules. The silver-toned dial features radial luminescent indexes, blued hands, three subsidiary counters, and a double-aperture Grande Date display below 12 o'clock. The lot includes an original fitted presentation box and certificate of origin.

Object description

Case Construction and Exterior Observations

The watch features a vertical tonneau-shaped profile executed in gilded stainless steel, measuring 37.3 mm in height and 40.8 mm in width. Visual observation shows a gold-toned case with a rounded stepped bezel, a fluted winding crown, and two round pushers operating the chronograph mechanism, while the source description characterizes them as olive-shaped push-pieces.

The cataloguer notes that the case back is secured by eight screws. In addition, the catalogue entry lists a black leather strap with a gilded metal buckle, whereas visual inspection of the provided photograph shows a brown leather strap with an alligator pattern.

Evidence for this section
  • “vertical “tonneau”-shaped, gentleman’s wristwatch, case-back screwed by eight screws”
  • “Gold-toned case with rounded stepped bezel, two round pushers, and a fluted winding crown.”
  • “Fitted with a brown alligator-pattern leather strap.”

Dial Configuration and Complications

The silver-coloured dial features radial luminescent indexes and blued subsidiary hands. At the 12 o'clock position, a half-instantaneous Grande Date mechanism is displayed via a double aperture, visibly reading '20' in the reference photograph.

Three subsidiary registers are located at 3, 6, and 9 o'clock. The source catalogues four complications: a 1/8-second chronograph operated by two pushers, a dragging 30-minute counter at 9 o'clock, a 12-hour counter at 6 o'clock alongside subsidiary seconds at 6, and the Grande Date aperture.

Evidence for this section
  • “silver colour dial with radial luminescent indexes, subsidiary seconds at 6 and four horological complications”
  • “· Dragging 30-minute counter (subsidiary dial at 9 o’clock) · 12-hour counter (subsidiary dial at 6 o’clock) · Half-instantaneous Grande Date of the month (double aperture at 12 o’clock)”
  • “Silver-toned dial with double-window big date aperture at the 12 o'clock position displaying date '20'.”

Reported Movement and Accompanying Materials

The internal mechanism and the case back are not visible in the provided image. According to the auctioneer, the watch is powered by self-winding calibre 4500, described as being based on an ETA 2892 A2 with additional Dubois-Dépraz modules.

Both the movement and case are listed by the source as unnumbered, though the piece is catalogued as number 25 of a 100-piece limited edition created in 2001 for the manufacture's centenary (1901–2001). The source notes that the dial, case, and movement are signed, and records the inclusion of an original fitted box and certificate of origin.

Evidence for this section
  • “Caliber 4500 (based on ETA 2892 A2 with additional modules by Dubois-Depraz)”
  • “Movement No. unnumbered Case No. unnumbered”
  • “Accessories original fitted box, certificate of origin”

Open research questions

  • Why does the catalogue specification state 'black leather strap' when the accompanying photograph depicts a brown alligator-pattern leather strap?
  • Where is the limited edition designation 'No. 25 / 100' marked on the watch if both movement and case are catalogued as unnumbered?
  • Which specific Dubois-Dépraz module components make up calibre 4500 on the ETA 2892 A2 base?
