Plenty of ladies' watches look pretty. Far fewer can back up the looks with a certified movement, and that is where the Mido Baroncelli Chronometer Lady M027.208.16.106.00 earns its place. Behind a shimmering mother-of-pearl dial set with diamond hour markers sits an automatic caliber that has passed the independent COSC chronometer tests.

The Baroncelli family takes its cue from Milan's Galleria Vittorio Emanuele II, the glass-domed 19th-century arcade famous for its graceful arches and refined detailing. That spirit shows in the slender hands, the polished 34mm steel case and the restrained layout, which lets the natural play of color in the mother-of-pearl do the talking. Inside, the Mido Caliber 80 chronometer uses a silicon balance spring and stores up to 80 hours of power, so the watch can sit on the dresser over a weekend and still be running on Monday.

At 9.1mm thick, it slips easily under a cuff, and the black leather strap with folding clasp keeps it secure and dressy. It suits someone who wants a single elegant automatic for the office, dinners and special occasions alike.
