Set in a striking 23-millimeter, polished stainless steel case, this Tank Solo watch from Cartier is the pinnacle of luxury. An elegant choice for women and men, the Tank Solo features a stainless steel bezel, deployment buckle and circular-grained crown set with a spinel cabochon. Through a scratch-resistant sapphire window, the opaline white dial has bold Roman-numeral hour markers and sword-shaped blue steel hands. The smooth black strap is made of alligator. Powered by Cartier’s own Cablibre 157 Swiss-quartz with two-hand movement, this silver-toned timepiece is also water resistant to 99 feet.
