Design
- Visible features
- • Hinged outer case back open revealing the gilt manual-wind movement signed ZENITH. • Movement plate stamped with serial number 7046624. • Prominent onion-style winding crown positioned at 3 o'clock relative to the movement orientation. • Attached soldered strap lugs holding an orange-brown alligator-grain patterned leather strap stamped 22 on the lining.
- Case Construction and Markings
- The double-hinged case measures 48.9 mm in diameter (listed as 58.5 mm including the crown, 57.6 mm lug-to-lug, and 14 mm thick) with a 22 mm lug width. The seller reports that the crystal is a replaced domed plastic crystal. According to the seller's listing, the interior of the case back bears multiple stamped marks: the Zenith name and star logo, the base-metal designation "Metal Blanc Garanti" (which the seller suggests translates to Guarantee White Metal, likely French silver plate), the case number 5281644 stamped twice, the letter "P", and the commemorative inscription "GRAND PRIX PARIS 1900".
- Object Identity and Conversion
- This object is an antique Zenith open-faced pocket watch movement that has been adapted into a wristwatch format. In its converted configuration, it features an onion-style winding crown positioned at 3 o'clock and attached soldered wristwatch lugs fitted with an orange-brown alligator-grain patterned leather strap. The seller dates the movement to 1906 based on serial number 7046624. Because this piece is an aftermarket conversion rather than an original factory wristwatch, the timing, source, and workshop origin of the wristwatch conversion remain unverified.
- Reported Dial Motif and Movement Details
- The supplied rear photograph displays only the open hinged case back, showing a gilt manual-wind movement signed "ZENITH" with serial number 7046624 alongside the balance assembly and winding mechanism. The dial side is not visible in the provided image. As reported by the seller, the dial is finished in deep hunter green enamel featuring a multi-colored roulette wheel motif in red, yellow, black, green, white, and gold, inscribed "Zenith Le Casino De Mone Carlo". The seller also reports a subsidiary seconds display positioned at 9 o'clock, white Breguet-style primary hour numerals, faint orange Breguet numerals for hours 13 through 24, and gold leaf-style hands.
