At 34.8 mm x 27.4 mm, the Tank Solo W5200025 case is rendered in a two-tone combination of 18K pink gold and steel. The silvered opaline dial is laid out with Roman numerals, and blued-steel sword-shaped hands provide a measured contrast across its surface. A sapphire crystal sits above the dial, while the 18K pink gold crown is set with a synthetic spinel cabochon — a detail characteristic of the Tank line.
Timekeeping is handled by a quartz movement, pairing reliable performance with the low-profile proportions the Tank Solo is known for. Water resistance is rated to 30 meters. The watch is finished with a black alligator skin strap secured by an 18K pink gold ardillon buckle, lending the piece a cohesive, dressed character throughout.
Reference W5200025 is presented complete with its original box and papers, making it a well-documented example of Cartier's long-running Tank Solo collection.
