Object description

Case and Exterior Construction

The watch features a large rectangular case executed in solid 18K rose gold, catalogued at 34 mm by 57 mm. The housing is described by the auctioneer as a two-body construction combining polished and brushed finishes, flanked by straight lugs with screw-set strap attachments and an 18K rose gold crown.

The timepiece is fitted with a black leather strap secured by a rose gold tang buckle. While the reverse is not shown in the solitary lot photograph, the auctioneer records that it possesses a transparent, see-through caseback that is signed and numbered.

Evidence for this section
  • “two-body solid 18K rose gold case polished and brushed”
  • “Case Size: 34mm x 57mm”
  • “see-through caseback signed and numbered”
  • “black leather strap with rose gold tang buckle”
  • “Rectangular rose gold case with straight lugs and screw-set strap attachments”

Dial Display and Calendar Layout

The dial layout incorporates elongated radial Roman numeral hour markers, which the source notes are relief-painted in silver satin with black outlines. Time is indicated via central blued steel spade-shaped hour and minute hands over the light-toned ground.

Calendar and astronomical complications are distributed across three distinct sectors: a 7-day retrograde day indicator arcs between 8 and 10 o'clock, a 31-day retrograde date scale balances it between 2 and 4 o'clock with blued steel indicators, and a semicircular moon phase window is positioned at 6 o'clock.

Evidence for this section
  • “blued steel spade-shaped hour and minute hands”
  • “The Roman numeral hour markers are relief painted in silver satin with black outline”
  • “7-day retrograde week calendar is positioned between 8 and 10 o'clock while the 31-day retrograde date calendar is between 2 and 4 o'clock. The moon phase display window is at 6”
  • “blued steel retrograde calendar indicators”

Movement and Seller Documentation

Internal operation is reported by the seller to rely on the automatic caliber 5740, stated to contain 29 jewels, provide a 48-hour power reserve, and bear the Seal of Geneva quality mark. These mechanical details, along with the reported limited edition run of 28 pieces, are derived entirely from seller documentation as neither the internal movement nor the case back engraving is visible in the solitary lot photograph.

The auction entry presents internal contradictions regarding the dial finish, describing it as a "cream dial" in the narrative text while tabulating the dial color as "Silver" in the specifications table. Furthermore, the lot is noted as pre-owned and is offered without its original box or papers, supplied instead in a gift box.

Evidence for this section
  • “caliber 5740 automatic movement with 29 jewels, stamped with the Seal of Geneva quality mark”
  • “produced in only 28 pieces”
  • “paired with a cream dial”
  • “Dial Color: Silver”
  • “Box: No Papers: No”
  • “presented in a gift box”

Open research questions

  • What specific individual edition number (e.g., X/28) is engraved on the case back or movement of this example?
  • Does the physical dial exhibit a silvered or cream/off-white base coloration under standard neutral lighting?
  • Can direct inspection of the movement confirm the presence of the Geneva Seal hallmark and caliber 5740 markings through the sapphire case back?
