Object description

Identity and Case Construction

This rectangular Art Deco tank-style wristwatch bears the Tiffany & Co. brand name on the dial. The seller reports that the piece dates to circa 1930 and that both the case and movement were provided by Swiss watchmaker E. Huguenin, while also claiming it was handcrafted by Tiffany & Co. The case is described as curved platinum and measures 36mm by 19mm.

Direct visual observation shows a rectangular curved case with elongated brancards and a cabochon-set winding crown. Internal case stamps, hallmarks, and case serial numbers are not recorded in this source or visible in the provided photograph.

Evidence for this section
  • “Both the case and movement were provided by Swiss watchmaking expert E. Huguenin.”
  • “Within the sleek and gently curved platinum case”
  • “36mm x 19mm”
  • “Circa 1930”
  • “Rectangular curved platinum case with elongated brancards and a cabochon-set winding crown.”

Dial Configuration and Gem-Setting

The dial is described by the source as an 'original restored dial' displaying stylized Art Deco numerals at the quarter hours along with hour markers. The seller notes that round diamonds are inset into the quarter numerals, while baguettes serve as markers for the remaining hours.

Visual observation confirms diamond-set Arabic quarter markers (12, 3, 6, and 9) and baguette-shaped indexes. Centrally placed blued steel hands track the time across an inner framed rectangle reading 'TIFFANY & Co.'.

Evidence for this section
  • “The time displays on the original restored dial, which is fitted with stylized Art Deco numerals at the quarter hours and markers.”
  • “The numerals are inset with round diamonds, while baguettes serve for the markers.”
  • “Distinct blued steel hands add contrast and a nice touch of color.”
  • “Dial features diamond-set Arabic quarter markers and baguette-shaped indexes.”
  • “Centrally placed blued steel hands set against an inner framed rectangle reading 'TIFFANY & Co.'.”

Reported Movement and Technical Limitations

The source describes the internal mechanism as a 'high-grade 17 jewel manual movement' with movement number 794946, attributed to maker E. Huguenin.

Because the case back has not been removed in the available imagery, internal movement markings, bridge signatures, caliber designation, and physical condition cannot be independently verified and rely entirely on vendor statements.

Evidence for this section
  • “Within the sleek and gently curved platinum case is a high-grade 17 jewel manual movement.”
  • “Movement #794946”
  • “Both the case and movement were provided by Swiss watchmaking expert E. Huguenin.”

Open research questions

  • What specific hallmarks, purity stamps, or serial numbers are struck on the interior of the platinum case back?
  • What caliber designation and manufacturer signatures are engraved directly on the movement bridges?
  • What specific restoration techniques were performed on the dial, and are the stones natural diamonds original to the setting?
