The Chopard L.U.C GMT One ref. 161943-5001 is a rose gold dual-time piece from the manufacture's in-house L.U.C line. The 42 mm rose gold case carries a smooth bezel and two signed rose gold crowns on the right flank — one for time-setting, one for GMT adjustment — a practical arrangement confirmed in the photos. The dial is brown with a sunburst finish at its center. A bold white 24-hour ring encircles the inner chapter, dividing day from night at a glance. White applied indexes and rose gold arrow hands complete the layout, with a date aperture at six o'clock. The dial is signed "L.U. Chopard Chronometer" and "Automatic GMT," confirming COSC chronometer certification. Power comes from the in-house caliber L.U.C 01.10-L, visible through the exhibition caseback engraved "GMT One" and "Chopard Manufacture." The movement plate reads "Adjusted to heat, cold, isochronism and five positions" — the standard of a true manufacture chronometer. A dark brown crocodile-pattern leather strap with a rose gold L.U.C-signed pin buckle completes the package. Excellent condition, watch only.
