AI Appraisal Estimate

This is a luxury men's wristwatch featuring the distinctive geometric design associated with the Hublot Big Bang Sang Bleu II collection, created in collaboration with tattoo artist Maxime Plescia-Buchi. The timepiece is characterized by its complex, multi-faceted 45mm case crafted from brushed and polished titanium. The architectural bezel is secured by six functional H-shaped screws. The dial is a skeletonized, open-work display that eliminates traditional hands in favor of three-dimensional, overlapping rhomboid discs that rotate to indicate hours and minutes, mirroring the aesthetic of geometric tattoo art. A black rubber strap is integrated into the case horns with a quick-release system. The watch appears to be a modern piece, likely manufactured within the last five years. While the image shows the iconic 'HUBLOT' logo and geometric hands, close inspection of the finishing on the case edges and the alignment of the internal components may require physical verification of authenticity, as this model is frequently replicated. The condition appears used with minor surface micro-scratches on the titanium facets, though the sapphire crystal remains clear. The movement is visible through the skeletonized face, showcasing industrial-style finishing.

I have conducted a visual examination of this Hublot Big Bang Sang Bleu II Titanium. The timepiece exhibits the intricate 'Maxime Plescia-Buchi' geometric architecture characterized by its overlapping rhumboid discs and multi-faceted 45mm titanium case. Condition-wise, the watch shows signs of light wear, specifically micro-marring on the high-polish facets of the titanium bezel and integrated lugs, though the sapphire crystal appears free of chips or surface abrasions. The skeletonized Unico movement displays the correct industrial finishing expected of this reference. The secondary market for Sang Bleu II models remains relatively stable but niche. While the original MSRP sits significantly higher, actual transaction prices for pre-owned titanium versions typically settle in the mid-to-high teens. This specific model benefits from the 'quick-release' strap system, which is in good condition, and the overall aesthetic remains highly desirable for collectors of geometric, avant-garde horology. Crucially, authentication via photography has significant limitations. The Sang Bleu II is a high-frequency target for 'super-clones.' To definitively confirm authenticity, I would require a physical inspection of the movement’s escapement, a weight check against manufacturer specifications, and a review of the 'Hublotista' digital NFC warranty or original box and papers. Without physical verification of the caliber HUB1240’s performance and finishing under a loupe, this valuation assumes the piece is genuine. Market value would be significantly impacted (reducing by 20-30%) if the original packaging and provenance documentation are missing.
