AI Appraisal Estimate

This is a luxury two-piece writing set from the Waterman Hemisphere collection, featuring a fountain pen and a matching mechanical pencil or ballpoint pen. Each instrument is crafted with a circular, brushed matte silver (likely frosted chrome or stainless steel) finish on the barrel and cap, providing a modern, sleek aesthetic. The pens are accented with gold-plated trim, including the signature Waterman articulated clip with its iconic central cutout and a black lacquered center band. The center bands are clearly engraved with 'WATERMAN' and 'PARIS,' signifying their French manufacture. The fountain pen features a two-tone steel or gold-plated nib with decorative scrollwork engraving and a black resin grip section. The construction shows high-quality craftsmanship characteristic of the 1990s to early 2000s era. Condition appears excellent with minimal signs of surface wear or oxidation on the metal components. The set is presented in a black, pebble-grained protective carry case with a contoured velvet-lined interior, suggesting proper storage and preservation of the original quality.

I have conducted a visual examination of this Waterman Hemisphere Duo Writing Set in Brushed Matte Silver with Gold-Plated Trim. Based on provided images, the set appears to be an authentic example of the original 'Hemisphere' series manufactured in France during the late 1990s. The 'Waterman Paris' engraving on the gold-plated center bands and the signature open-loop articulated clips are consistent with genuine period production. The condition is assessed as excellent; the brushed finish shows no significant 'pocket rash' or plating loss on the clips, though the fountain pen nib's internal feed and the mechanical internals of the ballpoint/pencil cannot be fully verified for functionality from photos alone. The market for mid-range Waterman sets is stable but saturated. The Hemisphere is valued as a reliable, entry-level luxury 'workhorse.' While the matte silver/gold combination is classic, it is less rare than the marbled lacquers or limited edition finishes of the same era. Comparables for single fountain pens in this finish range from $60 to $90, with full sets in original presentation cases commanding a premium. Value is significantly supported by the inclusion of the original pebble-grained case. However, authentication from images is limited. A physical inspection is required to confirm the absence of hairline cracks in the resin grip section and to verify the nib's material (standard gold-plated steel vs. 18k gold). Furthermore, I would need to observe ink flow and mechanical tension to certify 'Near Mint' status. Provenance or original purchase receipts would solidify the valuation at the higher end of the estimated range.
