Object description

Dial and Timekeeping Indications

The face is centered by a polychrome cloisonné enamel dial depicting two aeroplanes flying over continents and the ocean. Surrounding the central enamel medallion is an inner silvered brushed ring with minute calibrations, dot numerals, and luminous hands accompanied by sweep centre seconds. The dial is signed 'VULCAIN' below centre and inscribed 'Swiss N° 20/25' along the bottom edge.

An outer white ring features 12 Arabic numerals, reported by the auction catalogue as an outer revolving ring adjustable via a screw-down crown located at 4 o'clock.

Evidence for this section
  • “polychrome cloisonné enamel dial depicting two planes flying over the world and the sea, dot numerals, luminous hands, sweep centre seconds, silvered brushed ring with minute indication”
  • “outer revolving ring with 12 arabic numerals adjustable by screw down crown at 4 o'clock”
  • “Dial is signed 'VULCAIN' below centre and inscribed 'Swiss N° 20/25' along the bottom edge.”

Case Architecture and Operating Controls

The circular case measures 42 mm in diameter and is executed in 18K white gold, catalogued with a snap-on back. On the right side of the case, direct observation confirms three external controls: a round pusher at 2 o'clock and crowns at 3 and 4 o'clock.

According to the auctioneer, the push button at 2 o'clock functions to set the mechanical alarm, while the screw-down crown at 4 o'clock controls the revolving 12-hour ring.

Evidence for this section
  • “circular case, snap on back, push button at 2 o'clock to set the alarm”
  • “outer revolving ring with 12 arabic numerals adjustable by screw down crown at 4 o'clock”
  • “Case right side features a round pusher at 2 o'clock and crowns at 3 and 4 o'clock.”

Movement and Reported Accessories

The movement is identified in the catalogue as a 17-jewel Calibre V-10 mechanical movement, with case, dial, and movement all recorded as signed. Because the watch is depicted solely from the front, the movement and the snap-on case back are not visible for direct verification in the source photograph.

The lot description also notes the inclusion of a Vulcain Certificate, an International Guarantee dated 5 May 2009, a stainless steel Vulcain buckle, and an original fitted veneered presentation box with outer packaging; none of these items are shown in the primary lot image.

Evidence for this section
  • “Cal. V-10 mechanical movement, 17 jewels”
  • “case, dial and movement signed”
  • “With Vulcain Certificate, International Guarantee dated 5 May 2009, original fitted veneered presentation box and outer packaging.”

Open research questions

  • What specific hallmarks and reference or serial engravings appear on the snap-on case back?
  • What style of stainless steel Vulcain buckle (tang pin buckle or folding deployant) accompanied the piece?
  • What finishing and caliber engravings are present on the movement bridges of this Calibre V-10?
