The Tissot Heritage Porto Mechanical is for anyone who thinks a dress watch should have a little personality. Its tonneau case, inspired by Tissot's barrel-shaped designs of the 1910s and 1920s, curves gently along the wrist and stands apart from the sea of round watches at any dinner table.

Inside is the real draw: the hand-wound ETA 7001, a slim, classic manual caliber that drives the hours, minutes and a small seconds subdial at 6 o'clock. There is no rotor and no battery, just a few turns of the crown each morning. The white dial is laid out with tall Arabic numerals and pear-shaped poire hands, an Art Deco combination that suits the shaped case perfectly.

At 31.1mm across and 42.45mm long, the case has real presence while remaining slim at about 10.5mm, and the black leather strap keeps the look formal. It works as well with a tailored suit as it does with a crisp shirt and jeans.
