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.
