AI Appraisal Estimate

This is a luxury writing instrument set featuring a Waterman Hemisphere fountain pen and matching ballpoint pen. These items are presented in a custom-fitted black hard-shell storage case. The instruments feature a sophisticated matte silver (brushed steel) finish on the barrels and caps, contrasted by 23k gold-plated trim. This trim includes the iconic Waterman split clip, decorative center bands, and end caps. The fountain pen is equipped with a gold-plated steel nib, which appears to be a medium or fine grade. The center ring on both pens is clearly engraved with 'WATERMAN PARIS' and 'FRANCE', indicating their French manufacturing origin. The Hemisphere model is known for its slim, elegant profile and tapered ends, reflecting a classic late 20th-century to early 21st-century modern aesthetic. The condition appears to be excellent, categorized as 'New Old Stock' or lightly used, with no visible signs of metal oxidation, deep scratching, or ink staining on the section. The matte finish remains uniform across both pieces, and the gold plating shows a bright, high-shine lustre without visible thinning. The set demonstrates high-quality French craftsmanship and remains a popular choice for professional and ceremonial use.

I have examined the provided images of the Waterman Hemisphere Matte Silver with Gold Trim set. Based on my visual inspection, the set appears to be in 'New Old Stock' or 'Near Mint' condition. The matte stainless steel finish shows no signs of the typical 'pocket wear' or surface polishing common in used units, and the 23k gold plating retains its original electrolytic thickness. The hallmarks 'WATERMAN PARIS' and 'FRANCE' are consistent with genuine factory production from the late 1990s to early 2000s. The market for the Hemisphere collection remains stable; while not as rare as the Man 100 or Serénité lines, this specific finish remains highly desirable for its professional utility. Comparable sets in original presentation cases typically sell in the $150 range, with premiums for pristine nib condition. Limitations: A definitive valuation is restricted by the inability to physically inspect the fountain pen's feed for internal ink residue or cracks in the plastic section. I cannot verify the integrity of the cartridge/converter seal or the ballpoint's internal mechanical spring without tactile testing. Full authentication would require a high-magnification inspection of the nib tipping material and verification of the box's serial tracking if available. Provenance documentation, such as an original warranty booklet or purchase receipt, would further solidify the upper-tier valuation.
