Housed in an 18K yellow gold case with a steel case back, this Tank Solo Small presents the classic Tank form in its most understated proportions. The sapphire crystal protects a silvered opaline dial that frames Roman numerals with blued-steel sword-shaped hands, while the beaded 18K yellow gold crown is set with a synthetic spinel cabochon — a signature Cartier detail.
Power comes from a quartz movement, offering straightforward, low-maintenance timekeeping well suited to a precious-metal dress watch. The case offers 30 metres of water resistance, and the alligator-skin strap with round scales fastens via an 18K yellow gold ardillon buckle, keeping the overall look refined and unencumbered.
At 31mm x 24.4mm and just 5.55mm thick, the W5200002 sits with quiet elegance on the wrist. The combination of yellow gold, opaline Roman dial, and alligator strap makes this Tank Solo Small a considered choice for those drawn to the enduring geometry of Cartier's most celebrated case shape.
