Our combined 40+ years of luxury asset expertise underpins every authentication, appraisal, and buying decision. Sun-Fri 11 AM to 5:30 PM.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">New York-based luxury watchmakers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CJ William&#8217;s authentication desk is staffed by watchmakers trained in the New York luxury watch industry, with combined 40+ years of experience across Rolex, Patek Philippe, Audemars Piguet, Cartier, Richard Mille, and vintage collector references. Our team members have worked at authorized service centers and independent luxury watchmakers before joining CJ William. Each authentication draws on hands-on movement disassembly experience, factory technical documentation, and cross-referenced archival data from Rolex, Patek Philippe, and Audemars Piguet manufacturer records.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What our watchmakers actually verify<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Movement caliber verification: Rolex 3135\/3235\/4130\/3186, Patek 240Q\/324\/26330\/CH28-520, AP 3120\/3126\/3132\/3300 and equivalents<\/li><li>Case reference and serial number cross-check against manufacturer archives<\/li><li>Dial signature, printing quality, and applied indices under 10x-20x magnification<\/li><li>Rehaut engraving depth and font for Rolex references post-2005<\/li><li>Bracelet construction, end link fit, clasp mechanism verification<\/li><li>Tapisserie pattern integrity on AP Royal Oak dials<\/li><li>Geneva Seal or Patek Seal inspection on Patek movements<\/li><li>Vintage-specific verifications: lume type (radium\/tritium), matching serials, unpolished case criteria<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Hermes specialists for Birkin, Kelly, and Constance authentication<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Our Herm\u00e8s specialists authenticate Birkin, Kelly, Constance, and rare Herm\u00e8s references using Herm\u00e8s workshop reference data. Verifications include blind stamp (workshop year) identification, saddle stitch pattern analysis, leather grain characteristics for Togo\/Epsom\/Clemence\/Swift\/Chevre\/Barenia, hardware inspection (palladium, gold, rose gold, ruthenium), and CITES documentation review for exotic leathers. Special editions including Himalaya, Ostrich, Crocodile Porosus, and Alligator Mississippi are authenticated by our lead Herm\u00e8s specialist.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Antique silver, jewelry, and metals appraisers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Our antique silver desk authenticates Buccellati, Tiffany, Georg Jensen, and Puiforcat sterling using hallmark reference guides and workshop production records. Our jewelry desk includes GIA-trained gemologists for diamond grading (4Cs verification), colored stone identification, and estate jewelry maker attribution (Cartier, Van Cleef &#038; Arpels, Bulgari, Harry Winston, David Webb). XRF verification for precious metals content and karat verification for all gold, silver, and platinum acquisitions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why in-house expertise matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most South Florida luxury asset buyers outsource authentication to third-party services (7-14 day turnaround, third-party fees) or bypass authentication entirely (relying on visual inspection alone). CJ William&#8217;s in-house watchmaker and Herm\u00e8s specialist team means: same-day authentication for modern references, 24-48 hour authentication for vintage or complicated pieces, written authentication determinations for insurance and legal purposes, and offers based on verified authenticity rather than assumption. This is why CJ William pays premium offers on authenticated pieces \u2014 we know exactly what we are buying.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Continuing education and market intelligence<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Our team monitors auction results (Christie&#8217;s, Sotheby&#8217;s, Phillips), manufacturer archive updates, and secondary market trends to price offers accurately. We track daily Rolex and Patek secondary market data, quarterly Herm\u00e8s pricing shifts, and material commodity pricing for gold, silver, and platinum. Our 2026 valuation data is updated quarterly across all luxury asset categories.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Visit our team in Surfside<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Visit CJ William at 9573 Harding Avenue, Surfside FL 33154.
