A white dial, a black leather strap and a certified chronometer movement make the Mido Baroncelli Chronometer Si M027.408.16.018.00 about as classic as a modern automatic gets.

The 'Si' in the name refers to silicon, the material of the balance spring at the heart of the Caliber 80 Si. Silicon is non-magnetic and very stable, and paired with COSC chronometer certification it delivers accuracy you can rely on day after day. The movement also stores up to 80 hours of energy, far more than the roughly 40 hours typical of older automatics. Visually, the watch follows the Baroncelli code inspired by Milan's Galleria Vittorio Emanuele II: a gloss white dial, mixed applied indexes, slim dauphine hands and a neatly placed date.

The leather strap makes it lighter and dressier than the bracelet version, perfect for weddings, interviews and evenings out. At 40mm and 9.4mm thick, it sits well on most wrists and slides comfortably under a cuff.
