Fortis Swiss 17 Jewels Incabloc Pendant Watch

This is a vintage Swiss-made pendant watch by the manufacturer Fortis, likely dating from the mid-20th century (circa 1950s-1970s). The watch features a gold-toned circular case made of base metal, as indicated by internal markings. The primary aesthetic feature is a Fragonard-style 'fete galante' scene depicted in enamel on the front cover, showing a romantic pastoral couple in a landscape. The watch is suspended from a matching gold-toned curb link chain. Technically, the watch is equipped with a 17-jewel mechanical movement featuring an Incabloc shock protection system, a hallmark of mid-century Swiss horology. Based on the description provided, it contains the crown logo over the Fortis brand name and is stamped 'base metal swiss made' with the reference number 17103 near the movement. The item shows visible signs of aging, including wear to the gold plating and possible minor oxidation on the chain and case edges. The enamel scene remains the focal point, exhibiting a classic Rococo revival style common for decorative ladies' watches of that era.

I have carefully examined the provided details for this Fortis 17 Jewels Incabloc hunting-case pendant watch. My assessment confirms this is a mid-20th-century Swiss-made timepiece, likely produced between 1955 and 1965. The hallmark 17-jewel movement with Incabloc shock protection indicates a quality-tier mass-market mechanical movement of that era. The 'base metal' stamp is a critical factor, confirming the case is gold-plated or gold-toned rather than solid gold, which serves as a ceiling for its market value. The Fragonard-style enamel 'fete galante' scene is a popular Rococo revival motif that appeals to collectors of romantic or decorative horology. Current market demand for non-precious metal pendant watches remains steady but modest, with comparable Swiss pieces by brands like Fortis, Bucherer, or Oris typically selling in the $150 to $250 range depending on mechanical health. Evaluation of the images shows noticeable wear on the gold plating and the chain links, which slightly diminishes the 'mint' collectible status. Limitations: This evaluation is based on visual data only. A physical inspection is required to verify the movement's functionality, timing accuracy, and the presence of any internal corrosion. To fully authenticate the piece as a genuine Fortis production, I would need to inspect the bridge markings on the caliber itself. Long-term value is contingent upon the watch being in running condition; a non-functional movement would reduce the appraisal to strictly decorative value ($40-$70).
