A regulator in Breguet's Classique line, this reference 5187PT/15/986 brings the format into the house's most restrained dress-watch language. The platinum case and silver dial give it a cool, understated presence, while the off-center display architecture adds the asymmetry collectors seek in a regulator. An automatic movement powers the watch with a date complication. At 35.5mm and 8.5mm thick, it wears with the compact, slim profile the Classique is known for.
