If you want a dress watch that keeps time as well as it looks, the Mido Baroncelli Chronometer Si M027.408.11.011.00 is a compelling answer. Its movement is officially certified by COSC, the Swiss chronometer testing institute, and it is regulated by a silicon balance spring.

Silicon matters because it is light, unaffected by magnetism and resistant to temperature swings, all of which help a watch stay accurate in daily life near phones, laptops and speakers. Mido's Caliber 80 Si combines that hairspring with an 80-hour power reserve, so the watch can rest from Friday evening to Monday morning without stopping. The design stays true to the Baroncelli ethos, which draws on the elegance of Milan's Galleria Vittorio Emanuele II: a polished 40mm case, a lacquered white dial with applied indexes and double-sided hands that catch the light from every angle.

At 9.4mm thick on a steel bracelet with push-button folding clasp, it is comfortable, refined and easy to wear every day.
