The Vulcain 50s Presidents Chronograph 570157.311L is a refined men’s timepiece that blends vintage inspiration with modern Swiss precision. Its 42 mm stainless steel case frames a rich blue dial powered by the Swiss automatic Caliber V-57, beating at 28,800 vibrations per hour with 25 rubies for smooth, reliable performance. The chronograph layout includes a centre chronograph seconds hand, a 30-minute counter at 3 o’clock, a small seconds counter at 9 o’clock, and a date window at 6 o’clock, offering balanced functionality and classic symmetry. A scratch-resistant sapphire crystal protects the dial, while a sapphire exhibition caseback reveals the movement within. With 50 m water resistance, a black alligator leather strap, and a stainless steel deployant clasp, this 50s Presidents model delivers timeless elegance, mechanical depth, and everyday sophistication.
