Most automatic watches are round. The Mido Baroncelli Tonneau Lady is not, and that is precisely its charm. Reference M041.307.11.016.00 wraps a slim mechanical movement in a barrel-shaped steel case whose gentle curves follow the wrist rather than sitting on top of it.

Part of Mido's Baroncelli family, which since 1976 has taken inspiration from the arched elegance of Milan's Galleria Vittorio Emanuele II, the Tonneau adds double gadroons around the case rim for a subtle architectural flourish. The white dial carries twelve diamonds as hour markers, and the whole case measures just 7.5mm thick. That thin profile comes from Mido's Caliber 1192, based on the ETA 2892-A2, a celebrated slim automatic that offers up to 42 hours of power reserve and shows through the display back.

On the matching steel bracelet with a push-button folding clasp, it is bright, light and easy to live with, an appealing alternative for anyone who wants a dress watch that looks a little different from the crowd.
