AI Appraisal Estimate

This is a vintage writing instrument set by Waterman Paris, consisting of a fountain pen and a matching mechanical pencil or ballpoint pen. The set features a deep royal blue lacquer finish on slim, cylindrical barrels, likely made of brass. Each piece is accented with gold-plated trim, including the finials, center bands, and the iconic Waterman open-slot pocket clips. The interior of the presentation box is lined with white satin-like fabric and bears the Waterman Paris logo in gold lettering. The fountain pen appears to have a snap-on cap, and the mechanical instrument utilizes a twist or push mechanism. Notable condition indicators include small price tags or inventory stickers remaining on the clips ('2.59' and '4.68'), suggesting these may be New Old Stock (NOS). The finish appears glossy and well-preserved with no significant visible scratching, though some light shelf wear to the box is possible. This style is consistent with Waterman designs from the 1990s or early 2000s, renowned for their French craftsmanship and reliable performance in the mid-luxury writing market.

Based on my visual examination of this Waterman set, I identify it as the 'Hemisphere' model in Cobalt Blue with Gold Trim, dating to the late 1990s. The set includes a fountain pen and a matching ballpoint pen. The condition appears exceptional; the presence of original retail stickers and the pristine state of the lacquer suggest this is New Old Stock (NOS). The gold plating on the clips and bands shows no signs of brassing or oxidation, which is often a concern with pieces of this era. Market demand for the Hemisphere remains steady as it is considered a reliable, classic 'workhorse' luxury set. While not as rare as the Man 100 or Edson lines, findng a complete set in this specific colorway with the original presentation box adds a premium of approximately 20-30% over individual loose pieces. Recent auction comparables for NOS Hemisphere sets range from $90 to $150 depending on the nib material (steel vs. gold-plated). A primary limitation of this digital appraisal is the inability to inspect the fountain pen nib for ink residue or the internal converter/filling system for seal integrity. Furthermore, I cannot verify the mechanical function of the ballpoint twist mechanism. To provide a definitive authentication, I would require an in-person magnifying glass inspection of the 'France' hallmarks on the center bands and a physical test of the writing units. The current valuation assumes the nib is the standard gold-plated stainless steel variety common to this model.
