TAG Heuer 2000 Exclusive Chronograph 'St. Moritz 2006' Limited Edition

This is a stainless steel TAG Heuer wrist watch case back, identified by the model number CN111C and serial number TE9473. This specific piece is a limited edition release commemorating the '2006 St. Moritz Professional' world championship event, as indicated by the specific logo and text engraving on the case back. It is designated as number 559 out of a total production run of 700 units. The construction is a screw-down circular case back made of brushed and polished stainless steel. It features the standard TAG Heuer shield logo in the center, flanked by 'SWISS SINCE 1860' text. The watch appears to be a quartz-driven chronograph from the 2000 series (Exclusiv line). Regarding condition, the metal surfaces show significant signs of wear consistent with regular use, including numerous fine hairline scratches, some deeper scuffs, and a visible accumulation of debris or 'wrist gunk' around the edge where the case back meets the main body and near the pusher buttons. The engraving remains legible though softened by surface wear. The integrated bracelet is visible at the lugs, showing similar surface patina. This piece represents a niche sporting commemorative from the mid-2000s, blending high-end Swiss horology with professional skiing heritage.

I have examined the TAG Heuer 2000 Exclusive Chronograph 'St. Moritz 2006' Limited Edition (Ref. CN111C). This specific unit, numbered 559/700, represents a mid-2000s quartz professional sports watch with niche collectibility. The case back engravings, including the event logo and serial number TE9473, appear consistent with authentic TAG Heuer factory markings from this era. The condition is 'Fair to Good,' showing heavy signs of daily wear. There is significant 'wrist gunk' accumulation and surface oxidation around the threads and pushers, along with widespread hairline scratching. While the limited edition status provides a price floor, the aesthetic wear and quartz movement temper the valuation compared to contemporary automatic models. The market for the 2000 Exclusive series is stable, though 700 units is a relatively large run for this specific regional event. This valuation assumes the movement is functional and the bracelet is of full length. Limitations: Visual inspection cannot verify the movement's health or the integrity of the water-resistant seals. For full authentication, I would require an in-person inspection of the caliber to ensure it is the correct ETA-based movement, a pressure test for water resistance, and the original 'St. Moritz' edition packaging and paperwork to justify the high end of the valuation range.
